Abstract:

The post-peak stress strain relationship expression of intact rock cannot well reflect post peak properties of rock masses with joint, in order to obtain post peak stress-strain relationship suitable for rock masses with joint, based on the test data, based on the Kulun strength criterion, analysis evolution of post peak strength parameters of rock masses with joint. According to rock masses with joint under different confining pressure and fracture dip at different post peak behavior, the post peak stress-strain relationship is simplified as new kind type, regarding maximum principal strain as strain softening parameter, on the assumption cohesion and internal friction angle are the piecewise linear functions of maximum principal strain, the method of solving express of new post-peak stress-strain relationship of rock masses with joint is obtained.

Abstract:

Three types of physical tests were designed to study post failure behaviour and strength attenuation of fine sandstone. Tests include rock compression test, rock unloading test and rock block shear test. The stress-strain curves at different confining pressures had been obtained as well as axial strain-lateral strain curves. The differences of axial strain-lateral strain curves exhibit that stress peak point and the point of fault formation are apparently different for the rock. After the fault is generated, fractured rock slides on the fault surfaces, while confining pressure, material strength and structure effect decide the post failure behaviour. Damaged rock specimens were poured in concrete specimens as well as irregular blocks. Material strength of rock blocks was attained. Shear strength gradually attenuates with unloading points close to the peak. Past the stress peak, rock blocks from fractured rock still have considerable material strength. It is shown that there are differences of strength parameters obtained from direct shear test and triaxial test.

Abstract:

In order to build the post-peak strain softening model of rock, the evolution laws of rock parameters m,s were obtained by using the evolutionary mode of piecewise linear function regarding the maximum principle stress. Based on the nonlinear Hoek–Brown criterion, the analytical relationship of the rock strength parameters m,s, cohesion c, and friction angle φ has been developed by theoretical derivation. According to the analysis on the four different types of rock, it is found that, within the range from 0 to σ3min, the peak hardness of the rock becomes smaller as the confining pressure increases and the degree of rock fragmentation decreases as well. The post-peak stress-strain curves obtained from the developed softening model are in good agreement with the laboratory test results under different confining pressures. In conclusion, the analytical method is reasonable, and it can predict the post-peak mechanical behaviour of rock well, which provides a new thought for the rock-softening simulation.

Abstract:

Cambodian modernity was driven by the political agenda of the Sihanouk government beginning in the 1950s, and Cambodian rock and roll emerged in the 1960s in step with Sihanouk's ambitious national modernization project. Urban rockers were primarily upper-class male youths. In. the postcolonial era rock and roll was appropriated from abroad and given a unique Cambodian sound, while today's emerging hard rock music borrows foreign sociocultural references along with the music. Postmodern Cambodia and its diaspora have seen the evolution of a more diverse music subculture of alternative voices of hard rock bands and hip-hop artists, as well as post-bourgeois and post-male singers and songwriters.

Abstract:

The deterioration of rock mechanical properties under chemical-freezing-thawing-loading will seriously threaten the stability and safety of engineering rock mass, so the study of its constitutive model has very important theoretical and engineering application significance. In view of the deficiency that the existing statistical damage constitutive model cannot describe the nonlinear characteristics of the compaction stage and the post-peak shape, the compaction index is introduced to measure the stress-strain nonlinear characteristics caused by the iso-compression of the pores in the rock, and the post-peak correction coefficient is introduced to optimize the post-peak shape of rock loading. Assuming that the strength and failure of rock microunits obey the Weibull distribution, on the basis of using the Drucker-Prager strength criterion to measure the strength of rock microunits, a statistical damage model for rock considering the compaction stage and post-peak shape under chemical-freezing-thawing-loading is established. Finally, it is compared with the test curve. The results show that the calculation curve of the established chemical-freezing-thawing-loading rock statistical damage model has the same trend as the rock uniaxial compression test curve. Furthermore, it can better describe the rock stress-strain law with different chemical solutions and different freeze-thaw cycles, which fully reflects the rationality and accuracy of the constructed constitutive model. The research results can provide a theoretical basis for the calculation of deformation and failure of rocks under chemical-freezing-thawing-loading.

Abstract:

Rock-music and rock-culture, which is formed on its basis, are methods of entering into culture of post-industrial society described by D. Bell, E. Toffler, F. Fukuyama and others. The correlation between rock-culture and post-industrial culture is established in the aspects of values, rules, practices and identities. In rock culture we can see the formation of the following values: creativity, initiative and individualism. Independence of creativity becomes an ethic imperative. It is more important than techniques and professionalism, which are characteristic of industrial culture. Exaggerated prevalence of innovation over playing tradition strengthens the status and role of the author striving for the permanent re-creation of his own image and style. Another quality, which helps rock culture penetrate into postindustrial society, is assimilation of daily routine by creative activity. This factor initiates consciousness emancipation and breakdown of hierarchical social structures. Rock-culture, as well as post-industrial society, experiences decentralization, de-synchronization and de-standardization. Such social-cultural disorder correlates with marginalization of rock-culture. It forms amateurism as a normative attitude that is opposed to professionalism. Finally the above-mentioned changes entail the collapse of the existing “big” identities, which are substituted by “small group” identities in rock-culture characterized by small potential for internalization. This change of identities, their overlapping triggers the formation of mental plurality, tolerance to mutually exclusive values, normative settings, practices and symbols. Mental pluralism allows a person to change quickly life strategies, respond to external challenges. The stable boundaries between private and public, between art and everyday life are being destroyed in the rock-culture. At the same time, the author highlights the fact that within rock culture entering post-industrial culture is carried out by non-linear way, with expenses and contradictions.

And the results reveal that: (1) The post-peak stress - strain curves of specimens with joint inclination angle of 15°and complete specimens are basically the same, but the difference of post-peak stress - strain curves of specimens with the joint inclination angle from 30°to 60°and complete specimens is vary greatly; (2) The post-peak failure modes of specimen change with different joint inclination. The research result can reflect mechanics and deformation and damage characteristics under uniaxial compressive loading in the phase of post-peak of rock masses with different dip angle pre-existing persistent joints.

Full text

Abstract:

An integral component of the assessment of hazard and risk for landslides from large natural rock slopes is the examination of the likely consequences associated with failure. This in turn is inherently related to the post-failure velocity of the slide mass. This paper presents a decision analysis framework for assessment of the post-failure velocity of such slopes. The paper includes discussion of characteristics that influence the post-failure velocity and presents decision trees and supporting matrices to allow assessment of the likely post-failure velocity of translational and internally sheared compound landslides. These represent the most common classes of large rock landslides. The framework is based on data gathered from a large number of landslides from natural rock slopes and incorporates information from a study of excavated rock slopes. These landslides have been studied to determine the factors and characteristics of rock slope failures that influence the post-failure velocity. The framework provides an ability to semiquantitatively assess the uncertainty in prediction of the likely post-failure velocity and identify critical areas of investigation, which would allow for reduction of this uncertainty. The method is expected to be of most use in a quantitative or qualitative risk-based analysis for landslide safety management.

Abstract:

Considering the characteristic that rock mass can transform from brittleness to plasticity and the dynamic change of post-peak strength parameters of the rock mass, the invariability of elastic modulus and poisson's ratio, constitutive model of rock mass could be described with the characteristic that strength parameters obey different Mohr-Coulomb failure criterions under different plastic strains. This model may reflect the post-peak subsequent characteristics of rock mass and the fact that rock mass can transform from brittleness to plasticity with the increase of confining pressure. Numerical calculation is applied to simulate the triaxial compression test under different confining pressures and underground engineering example, which proves that this model has the characteristic of reflecting the damage extent of surrounding rock.

Abstract:

Until the late 1970s rock music in Poland was hidden behind many different labels, such as ‘music of a young generation’, ‘youth music’ or ‘big beat’, usually meaning something, if not pejorative, at least suspicious. Having the flavour of a forbidden fruit, genuine rock functioned quite successfully, mostly through independent circulation, not only as a specific form of art, but, first of all, as a symbol of protest against an existing political and social order (it does not matter if we call it ‘communistic’ or ‘capitalistic’); it was a symbol of independence and freedom.

Abstract:

In the case of fastenings on rock, as a result of the variability, it is quite difficult to make a preliminary assessment of the load-bearing capacity of rock as a base material. This paper therefore investigates which rock parameters next to an anchor position have an influence on the load-bearing capacity. For this purpose, tests are carried out on post-installed anchors in different lithologies in eastern Austria. It can be shown that the joint weathering has an influence on the load-bearing capacity of post-installed anchors and conclusions can be made about joint weathering by means of rebound hammer. Rebound values can therefore also be used to draw conclusions about the rock quality as a base material for post-installed anchors. Nevertheless, a combined optical assessment of the base material is recommended as an adequate method.

A conviction that rock is the central manifestation of the post-War mass culture and the most common form of mass cultural activity, seems undoubted for rock analysts. The question as to whether rock music is able to play any significant role in a process of political change evokes, however, scepticism rather than endorsement (Rosselson 1979; Hibbard and Kaleialoha 1983; Orman 1984; Pattison 1987; Grossberg 1991).

Abstract:

The functions and meanings of the global discourse of American and British rock in national literatures have hardly been studied so far. This article focuses on the very interesting case of Spanish literature after Franco. The central question is: How has rock functioned in the literature of the new Spain, both as intertext and as cultural memory? To be more specific, the main purpose of this contribution is to study the presence, functions and meanings of rock in the narratives of two leading authors of two generations of post-Franco novelists: Antonio Muñoz Molina (1956) and Ray Loriga (1967). Particular attention will be paid to the complicated processes of memory and oblivion articulated by explicit and implicit references to rock in the pivotal novels El jinete polaco (Muñoz Molina 1991) and Héroes (Loriga 1993), and to their functions and meanings in the historical-cultural process of memory and trauma in post-Franco Spain.

Full text

Abstract:

To control the large deformation that occurs in deep shaft-surrounding rock, the post-peak strain-softening characteristics of deep jointed rock mass are discussed in detail. An equivalent post-peak strain-softening model of jointed rock mass is established based on continuum theory and the geological strength index surrounding rock grading system, and numerical simulations are performed using FLAC3D software. The convergence-constraint method is used to analyze the rock support structure interaction mechanism. A composiste support technique is proposed in combination with actual field breakage conditions. During the initial support stage, high-strength anchors are used to release the rock stress, and high-stiffness secondary support is provided by well rings and poured concrete. This support technology is applied in the accessory well of a coal mine in Niaoshan, Heilongjiang, China. The stability of the surrounding rock support structure is calculated and analyzed by comparing the ideal elastic-plastic model and equivalent jointed rock mass strain-softening model. The results show that a support structure designed based on the ideal elastic-plastic model cannot meet the stability requirements of the surrounding rock and that radial deformation of the surrounding rock reaches 300 mm. The support structure designed based on the equivalent joint strain-softening model has a convergence rate of surrounding rock deformation of less than 1 mm/d after 35 days of application. The surrounding rock deformation is finally controlled at 140 mm, indicating successful application of the support technology.

Abstract:

This article argues that after the disintegration of Yugoslavia, Yugoslav rock music lost little cultural value and is still a prominent trigger of vernacular memories of the socialist Yugoslav past, as well as a vehicle of socio-political commentary in post-Yugoslav contexts. In this view, music is understood as a galvaniser of affective relationships to that past and to post-Yugoslav presents. In the first part of the article, the author discusses the theoretical and practical implications of digitally mediated music as immersive affective environments, working within the framework of media archaeology and a digital archives approach. It is argued that Yugoslav rock has retained its potency and appeal, where today, in a post-Yugoslavia context, it presents an outlet for the recomposition of musical preferences through nostalgia and opposition to the post-1991 socio-political developments. In the second part of the article, focusing on Facebook and YouTube, the author investigates how Yugoslav rock has been reframed in social media and how fragments of the country’s past are reframed in digital media environments. A qualitative multimodal discourse analysis is employed here to investigate a selection of fan pages of rock musicians and bands.

Full text

Abstract:

The process of stress-induced fracturing around underground excavations is associated with dilatancy-bulking behavior of the fractured rock. Due to the importance in earth science and engineering design, this paper presents an experimental investigation of rock dilatancy-bulking behavior based on triaxial loading and unloading tests carried out on weak sandstone samples from the Gubei colliery. Through experimental and theoretical analyses, it is found that the volume increase of stress-fractured rock can be divided into two groups: (1) pre-peak dilatancy due to crack opening and propagation, (2) post-peak bulking by the sliding, rotate or detachment of rock blocks. And the post-peak bulking deformation is the main cause of the rock volume expansion. Moreover, the evolution of characteristic stresses and dilation angle show strong pressure dependence, which means that confining pressure strongly inhibits dilatancy-bulking behavior. It also indicates that the rock response under loading and unloading conditions is substantially different.

Abstract Glaciated valleys of the Dalton Range in the south-west Yukon Territory are dominated by rock glaciers identified as glacier ice-cored debris systems. The two rock glaciers studied have different amounts of deformation at present, resulting from post-formation mechanics. The primary formation of lobes of the rock glaciers resulted from periods of glacier activity in the Neoglacial, although older lobes, probably late Pleistocene in age, occur below the Neoglacial lobes. The hydrological systems of the rock glaciers have played a major role in the post-formation deformation of the land forms and the present drainage system is entirely sub-surface. The explanation for the extensive occurrence of rock glaciers in the Dalton Range is lithological as a result of the high susceptibility of the Upper Jurassic/Lower Cretaceous sediments to frost action and glacier erosion.

Abstract:

The floor heave is one of the key factors that can restrict high-efficiency and safety mining, especially in the deep roadways with soft rock. Considering the influences of rock fracturing over time on rock mass properties, a case study of the floor heave evolution and rock bolts reinforcement technology was performed in this paper. A numerical simulation was used to study the stress-strain state and displacement of surrounding rocks. It was found that significant floor heave caused by nonlinear deformation of laminated immediate floor under an increase in rock fracturing. The post-peak strain regions appear in the bottom corners of the roadway, after which strata in the immediate floor are destroyed one by one. The joint spacing of 0.45 m on the immediate floor is critical. At this step, post-peak strain regions merge in the central part of the roadway floor, which is the cause of uncontrolled floor heave. Rock bolts reinforcement was proposed to control the floor heave. Three floor support schemes with two types of support elements, different bolt orientations, and lengths of reinforcement were studied. The numerical simulation demonstrated that after reinforcement, post-peak plastic strain in the floor strata was reduced effectively. The optimal floor support scheme and depth of reinforcement were determined by the allowable floor heave. Ideally, the floor heaves could be reduced by rock bolts with a steel belt installed according to the support scheme III and reinforcement length of 2.0 m for outer bolts and 3.0 m for central bolts.

Abstract:

AbstractThe ‘post-’ in both post-identity politics and post-genre musical practice refers to the same thing. Through readings of Taylor Swift's ‘Shake It Off’, Diplo's description of his practice as a DJ, producer and impresario, Sasha Frere-Jones's infamousNew Yorkerpiece on indie rock miscegenation, and critical race theorists Cristina Beltran and Jared Sexton's critiques of post-racial politics, I demonstrate that progress past traditional commitments to white racial purity is both the defining characteristic of post-racial whiteness, and what makes multigenre pop practice count as post-genre. The ‘post-’ in post-identityis what distinguishes post-genre practice from supposedly more primitive forms of genre transgression, such as the love & theft-style cultural appropriation Eric Lott identifies in 19th century blackface minstrelsy or Pitbull's Latin American style racial/musical mestizaje.

Abstract:

The shamanistic interpretation of hunter-gatherer rock arts has in recent years been heavily criticized. Much of this criticism draws on some of the same fundamental flaws in the shamanistic approach to understanding rock arts. In this article I briefly outline what it is about shamanism and its use in rock-art research that both sides of the debate have got wrong. Taking southern African hunter-gatherer rock art as a starting point, I demonstrate a new way of understanding rock art is indeed possible. I then explore the possibilities of this approach by examining rock art from the post Palaeolithic in Spain, and the Palaeolithic cave art of western Europe.

Abstract:

Rock permeability is important in civil and geo-hydraulic engineering, the mining and petroleum industries, and in environmental and engineering geology. In this paper, considering the mutual hydro-mechanical response between stress-induced permeability and damage, a coupled mathematical model for solid deformation and gas flow in the coal or rock was established and an attempt is made to investigate the rock permeability evolution, fracture patterns, and flow vectors in rock samples at the scale of usual laboratory samples as well as the relation between permeability and stress induced damage in connection with the complete strain-stress process of loaded rocks. Numerical simulations show that the permeability of rock was not constant, closely related to the state of stress, but varied with the stress and strain states in the rocks. Microcracking, resulting from the concentration of stress on relatively weak rock elements, triggers successive crack initiation and propagation that in turn leads to permeability enhancement. Prior to the peak strength, the permeability decreases with increasing load. A dramatic increase in permeability occurs in the post-peak stress-strain region due to the catastrophic collapse of microstructure in rock. Moreover, the permeability of rock in post-peak stress-strain region is much higher that that of in pre-peak region. Such intensive studies of gas flow in stressed heterogeneous rocks are useful as initial approaches to many engineering problems in mining and petroleum industries.

Abstract:

AbstractThis paper focuses on the case analysis of the memorial to the victims of state terror – the Wall of Grief (Stena skorbi) – which was unveiled on the eve of the 100th anniversary of the November 7, 1917, coup d’état. Using this example, we have attempted to elaborate a structure for a more complex analysis of the memory of past regimes’ manifestation and to create a methodological base for their comparison. We have based our research on the discourse theory by the so-called Essex School, the social semiotics by Kress, and the procedures of the critical discourse analysis. The procedure that we have considered relevant consists of the following: (a) description of the social context in which the memorial was manifested as a piece of evidence; (b) semiotic analysis of the memorial artifact; (c) analysis of verbal practices, as well as written and spoken texts that “explained” the memorial; and (d) analysis of nonverbal practices, namely, rituals. On the basis of our case study, we have come to the conclusion that when carrying out a semiotic analysis and the analysis of verbal and nonverbal practices in the case of the Russian public discourse, it is especially relevant to pay attention not only to widening vs. narrowing of the chronological framework, generalization vs. concretization, and specification of the traumatic experience but also to the question of framing of the memorial. In regard to the semiotic analysis, the extent of indexicality is considered to be very important in the sense of the bodily connection with an element of the commemorated event that bestows “truthfulness” and authenticity on the memorial. We assume that particularly present-day Russia, where explicit attempts to reinterpret the history of the authoritarian communist state and attempts to instrumentalize the totalitarian period according to the vector of the current political direction may be seen, is a relevant object of this kind of research.

Abstract:

Summary Legacy crushed rock analysis, as applied to unconventional formations, has shown great success in evaluating total porosity and water saturation over the previous three decades. The procedure of crushing rock into small particles improves the efficiency of fluid recovery and grain volume measurements in a laboratory environment. However, a caveat to crushed rock analysis is that water and volatile hydrocarbons evaporate from the rock during the preparatory crushing process, causing significant uncertainty in water saturation assessment. A modified crushed rock analysis incorporates nuclear magnetic resonance (NMR) measurements before and after the crushing process to quantify the volume of fluid loss. The advancements improve the overall total saturation quantification. However, challenges remain in the quantification of partitioned water and hydrocarbon loss currently derived from the NMR spectrum along with its uncertainty. Furthermore, pressure decay permeability from crushed rock analysis has been reported to have two to three orders of magnitude difference between different laboratories. The calculated pressure decay permeability of the same rock could even vary by several orders of magnitude with different crushed sizes, which questions the quality of the crushed pressure decay permeability. In this paper, we introduce an intact rock analysis workflow on unconventional cores for improved assessment of water saturation and enhanced quantification of fast pressure decay matrix permeability from intact rock. The workflow starts with acquisition of NMR T2 and bulk density measurements on the as-received state intact rock. Instead of crushing the rock, the intact rock is directly transferred to a retort chamber and heated to 300°C for thermal extraction. The volumes of thermally recovered fluids are quantified through an image-based process. The grain volume measurement and a second NMR T2 measurement are performed on post-retort intact rock. The pressure decay curve during the grain volume measurement is then used for calculating the pressure decay matrix permeability. Total porosity is calculated using the bulk volume and grain volume of the rock. Water saturation is quantified using the total volume of recovered water. In addition, the twin as-received-state rocks are processed through the crushed rock analysis workflow for an apple-to-apple comparison. Meanwhile, the pressure decay permeability of the post-retort intact sample is cross-validated against the steady-state gas permeability of the same post-retort sample. The introduced workflow has been tested successfully on different formations, including Bakken, Bone Spring, Eagle Ford, Cotton Valley, and Niobrara. The results show that total porosities calculated from intact rock analysis are consistent with total porosities from crushed rock analysis, while water saturations from the new workflow are an average 8% saturation unit (SU) [0.2 to 0.7% porosity unit (PU) of bulk volume water (BVW)] higher than those from the prior crushed rock workflows. The study also indicates that for some formations (e.g., Bone Spring), the fluid loss during the crushing process is dominated by water; however, for some other formations (e.g., Bakken), the hydrocarbon loss is significant. Pressure decay permeability quantified using intact rock analysis is also confirmed within an order of magnitude of steady-state matrix permeability.
