Full textEsta dissertação apresenta uma comparação dos métodos utilizados para análise da estabilidade dinâmica de taludes de solo através de métodos pseudoestáticos (equilíbrio limite) e dinâmicos (método dos elementos finitos). Com ambos os métodos foram estudadas as características de estabilidade de 47 perfis de taludes da Costa Verde, faixa litorânea na cidade de Lima, Peru, abrigando importante rodovia ladeada por 8,25 km de taludes íngremes e de grande altura. Nesta região a ocorrência de sismos é freqüente, devido ao fenômeno da subducção da placa de Nazca sob a placa Continental Sul-Americana. O sismo de projeto foi estabelecido em relação a estudos regionais de risco sísmico e o acelerograma utilizado corresponde ao registrado no terremoto de Lima de 03 de outubro de 1974, normalizado para uma aceleração máxima de projeto de 0,33g. Os resultado obtidos pelos métodos pseudo-estáticos e pelo método dos elementos finitos apresentam diferenças em alguns dos perfis analisados, provavelmente porque os métodos pseudo-estáticos geralmente consideram as forças de inércia constantes na fatia e sem mudança de sentido durante o período da excitação sísmica.
This thesis presents a comparison between the methods generally used for dynamic stability analysis of earth slopes, based either on a pseudo-static approach (limit equilibrium method) or on a dynamic approach (finite element method). Forty-seven profiles from the Costa Verde slopes located in Lima, Peru, were analyzed with both classes of methods. In this region seismic activity is quite common, caused by subduction of the Nazca plate into the South American Plate. The design seism was established from regional studies of seismic risks and the accelerogram used in this research corresponds to the seismic records from a major earthquake that hit Lima on October 3rd, 1974, herein normalized with respect to the maximum design acceleration of 0,33g. The results obtained with pseudo-static and the finite element methods presented differences in some specific soil profiles, probably because the pseudostatic methods admit that the inertial forces are constants through a soil slice and there are no changes in direction of the dynamic forces during the period of seismic excitation.

reliability method. In both of those failure types, two different failure criteria namely, Coulomb linear and Barton Bandis non-linear failure criteria are utilized in the development of the probabilistic models. Due to the iterative nature of the AFOSM method, analyzing spreadsheets have been developed in order to carry out the computations. The developed spreadsheets are called &ldquo
Plane Slope Analyzer (PSA)&rdquo
and &ldquo
Wedge Slope Analyzer (WSA)&rdquo
. The developed probabilistic models and their spreadsheets are verified by investigating the affect of rock and slope parameters such as, ground water level, slope height, cohesion, friction angle, and joint wall compressive strength (JCS) and their distribution types on the reliability index (&
#946
), and probability of slope failure (PF). In this study, different probability distributions are used and the inverse transformation formulas of their non-normal variates to their equivalent normal ones are developed as well. In addition, the wedge failure case is also modeled by using system reliability approach and then the results of conventional probability of failure and the system reliability approach are compared.

Full textOs projetos geotécnicos são, em geral, avaliados através do cálculo de um coeficiente de segurança, obtido de forma determinística. A presente pesquisa tem como objetivo a comparação de dois métodos probabilísticos (Estimativas Pontuais e Segundo Momento) empregados em análises de estabilidade. Os métodos probabilísticos quantificam as incertezas oriundas da variabilidade dos parâmetros geotécnicos, calculando-se um índice de confiabilidade (beta), que expressa o quanto o fator de segurança é confiável. No entanto, o índice b é um parâmetro relativo, pois não exprime todas as incertezas contidas em um projeto geotécnico. O trabalho apresenta uma comparação das análises probabilísticas de estabilidade da barragem de Curuá-Una, no Pará, e de um muro de arrimo, em São Fidélis, no Estado do Rio de Janeiro. No caso da barragem, estudou-se a influência de um eventual aumento no nível d´água do reservatório no cálculo da probabilidade de ruptura. Para o muro, foram consideradas diversas alturas do nível d´água no retroaterro a montante. As análises enfocaram, ainda, detalhes dos métodos probabilísticos, no que se refere à aplicabilidade para projetos práticos. Verificou-se que o método do Segundo Momento é de mais fácil utilização em geotecnia. Recomenda-se, portanto, a sua aplicação em conjunto com as análises determinísticas, mais usuais na prática.
Geotechnical projects are generaly assessed through the calculus of the safety factor obtained by deterministic methodologies. The purpose of the present research work is to compare two probabilistic methods (Estimate Punctual and Second Moment) employed in stability analyses. Probabilistic methods quantify the uncertainties derived from the variability of geotechnical parameters, calculating a confidence ratio that expresses how reliable the safety factor is. However, the ratio is a relative parameter, since it does not account for all the uncertainties contained in a geotechnical project. In view of this situation, the study compares the stability probabilistic analyses of Curuá-Una dam, in Pará, and those of a retaining wall in São Fidélis, Rio de Janeiro. Regarding the dam, the influence of a possible rise in the resevoir water level in the calculus of failure probability has been investigated. In respect to the wall, several water levels have been considered in the upstream backfill. Moreover, the analyses have focused on the details of probabilistic methods and their application to practical projects. It has been verified that the Second Moment Method is more easily employed in geothecnics. Therefore, it is recommended that it should be applied together with the deterministic analyses currently used in practice.

Full textENGLISH ABSTRACT: Riprap is commonly used as an erosion protection measure around the world. In some cases, for example when constructing bed arrestors, riprap has to be designed to be stable on steep slopes. The literature shows that the problem of incipient motion is reasonably well understood, but existing hydraulic design methods are found to be largely unreliable. The main objective of this study is to improve the understanding of the different factors affecting incipient motion in order to furnish the prospective design engineer with a reliable method for sizing riprap on steep slopes adequately. Eight existing theories dealing with the threshold of incipient motion are reviewed, of which Liu’s work (1957) seems most promising. Naturally, the required median rock diameter of the riprap is reasonably large (due to the steep slopes), with high particle Reynolds numbers. However, little data is available for these flow conditions. Data collected from 12 large scale laboratory tests carried out for this research indicate that the dimensionless Movability Number is in fact constant for large particle Reynolds numbers. For design purposes, the recommended Movability Number which emerged from this study is 0.18, provided that the steep bed slope is taken into account, and that the theoretical settling velocity is calculated using an accurate drag coefficient and the d90 sieve size. A comparison of the laboratory data with design equations showed that a large variety of results are obtained, which supports the need for this study. Finally, it was shown that a calibrated one dimensional hydrodynamic model can be used by the practicing engineer to extract the hydraulic properties needed for applying Liu’s theory. It was found that the ratio ks/d90 = 0.81 may be applied to estimate the bed roughness for the grading used in this study.
AFRIKAANSE OPSOMMING: Stortklip is ‘n metode wat wêreldwyd gebruik word om erosie te voorkom. In sommige gevalle, byvoorbeeld vir die konstruksie van erosietrappe, moet stortklip teen steil hellings spesifiek ontwerp word om stabiliteit te verseker. Die literatuur beskryf die probleem van aanvanklike beweging redelik goed, maar dit is bevind dat die bestaande ontwerpmetodes grotendeels onbetroubaar is. Die hoofdoelwit van hierdie ondersoek was om die faktore wat beweging van stortklip veroorsaak, beter te verstaan en ‘n betroubare metode te ontwikkel wat ’n ingenieur kan aanwend om stortklipbeskerming wat op steil hellings geplaas word te ontwerp. Agt verskillende metodes wat die begin van beweging beskryf is bestudeer, en dit wil voorkom asof die Liu teorie van 1957 die grootste potensiaal het. As gevolg van die steil hellings wat ondersoek word, is die benodigde klipgroote redelik groot wat weereens die oorsaak is vir ‘n hoë deeltjie Reynolds getal is. In die literatuur kon geen data gevind word vir so ‘n vloeitoestand nie. Daarom is 12 laboratoriumtoetse gedoen en daar is gevind dat die Mobiliteitsgetal redelik konstant is vir groot deeltjie Reynoldsgetalle. Vir onwerpdoeleindes word ‘n Mobiliteitsgetal van 0.18 aanbeveel, met die voorwaarde dat die bodemhelling in ag geneem word, en dat die teoretiese valsnelheid bereken word met die d90 klipgroote en ‘n akkurate sleurkoëffisiënt. Verder is gevind dat die labaratorium data die voorspellings van die bestaande ontwerpvergelykings nie bevredigend pas nie. Dit ondersteun die behoefte vir hierdie studie. Om die bogenoemde bevindings vir praktiese probleme bruikbaar te maak, is daar gewys dat ‘n gekalibreerde een dimensionale hydrodinamiese rekenaarmodel gebruik kan word om die nodige hidrouliese eienskappe te verkry om die Liu teorie toe te pas. Dit is bevind dat die verhouding ks/d90 = 0.81 ‘n goeie benadering vir die hidrouliese ruheid kan voorsien.

Full textNeste trabalho o método dos elementos finitos é empregado para analisar a estabilidade de taludes em solo solapados por voçorocas. Muitos dos deslizamentos de solo que ocorrem em taludes e encostas têm sido causados pelo fenômeno de voçorocas, o resultado de um processo de erosão de solos muito complexo. Uma breve revisão sobre a formação e o crescimento de voçorocas, bem como sobre os seus efeitos na estabilidade de taludes em solo, é feita neste trabalho. Exemplos ilustrativos da aplicação desta técnica para alguns casos de taludes e encostas erodidos por voçorocas são apresentados, incluindo-se duas análises numéricas da estabilidade de encostas situadas na cidade de Goiânia - GO. Dificuldades numéricas devido à baixa taxa de convergência da solução nas proximidades do colapso do talude são também discutidas.
In this work the finite element method is employed to analyze the stability of soil slopes undermined by voçorocas (gulling). Many of the shear slides occurred in both natural slopes and embankments have been caused by the phenomenon of voçorocas, the outcome of a very complex soil erosion mechanism. A brief review about the formation and growing of voçorocas, as well as an overview of their effects on soil slope stability, are made in this work. In the numerical simulation by the finite element method, the potential slip surface is identified through the progressive formation of a region of yielded soil as the erosion process advances. A simple model, consisting of incremental excavations of soil near the foot of the slope, is used in this work to represent the undermining mechanism. Illustrative examples of this technique are presented for some cases of natural soil slopes eroded by voçorocas in the city of Goiania - GO. Numerical difficulties due to the poor convergence of the solution near the soil collapse are also discussed.
