As the best seismic indicator of shear modulus, shear-wave velocity is an important property in engineering problems in near-surface site characterization. Several surface-wave methods have been developed to obtain the subsurface shear-wave velocity structure. This thesis compared three surface-wave methods, Spectral Analysis of Surface Waves (SASW) (Nazarian et al., 1983), Multichannel Analysis of Surface Waves (MASW) (Park et al., 1999), and Refraction Microtremor (ReMi) (Louie, 2001), to determine which method gives the best estimation of the 1-D shear-wave velocity profile of near-surface soils. We collected seismic data at three sites in the greater Boston area where there are direct measurements of shear-wave velocities for comparison. The three methods were compared in terms of accuracy and precision. Overall, the MASW and the ReMi methods have comparable quality of accuracy, whereas the SASW method is the least accurate method with the highest percentage differences with direct measurements. The MASW method is the most precise method among the three methods with the smallest standard deviations. In general, the MASW method is concluded to be the best surface-wave method in determining the shear-wave velocities of the subsurface structure in the greater Boston area

Texto completoThis dissertation presents the spectral-analysis-of-surface-waves (SASW) method as a tool for obtaining the variations in the modulus shear (Gmax) with depth in the field of very small strains (below 0,001%). The SASW method is a nondestructive in situ seismic method, based on the generation and measurement of Rayleigh wave and on its dispersive characteristic nature. Throughout the implementation of an impact on the soil surface and the detection of the wave at various points by two receptors a dispersion curve is constructed (phase velocity versus wave-length). This dispersion curve is then inverted. Inversion is an analytical process for reconstructing the shear wave velocity profile from the experimental field. The shear modulus of each layer is readily obtained from the shear wave velocity profile. The theoretical content of the dissertation presents dynamic properties of the soils and is described in the equations that dominate the propagation of elastic waves, both in homogeneous media and in stratified media. The methodology developed to obtain the dispersion curves through the implementation of SASW test is defined, and results from tests carried out at the University Campus in São Paulo are presented and compared with values obtained from correlations based on SPT tests. These comparisons indicate that the SASW method is a good alternative to determine the profile of stiffness (Gmax) of the soil, agreeing with the level of deformation involved in the tests. Studies on the methods sensitivity are developed to verify the influence on the changing of the parameters given (natural unit weight, Poisson coefficient and thickness of layers) in reduction of data (inversion) on the final profile of VS. The conclusion is that the Poisson coefficient is the parameter with greater influence.

Texto completoLandslides affect many clay slopes in the world and regularly threaten people in urban areas mountainous. These landslides are characterized by a slow velocity but they may suddenly liquefy and accelerate unexpectedly. The solid-liquid transition on the clay has been studied of Trièves region (French Alps) using rheological experiments. They have shown the yield stress thixotropic behavior with a viscosity bifurcation which can explain the catastrophic fluidization observed in the field. This loss of material stiffness can be followed by a drop in the shear wave velocity (Vs). Inclined plane test and field experiments (Pont-Bourquin landslides in Switzerland) have both shown a precursor drop of Vs indicating that it could be a good proxy for monitoring unstable clay slope

Texto completoMagnetic Resonance Elastography (MRE) is a imaging technique, recognized as a pertinent method for the mechanical characterization of human tissue in vivo. It offersa particular interest in clinical diagnosis because the development of a pathological process is often accompanied by modifications of the mechanical properties of diseased tissues. MRE consists of recording, along the three spatial dimensions, the displacement field induced by the propagation of a shear wave generated by excitation of the investigated tissue. Mechanical parameters such as shear wave velocity, v, and shear moduli, G' and G'', can then be mapped. The quantification of the mechanical parameters depends on the frequency of the mechanical excitation, fexc, the spatial resolution, a, the amplitude of the induced displacement field, A and the amplitude of the curl field displacement, q, with associated measurement errors, ΔA and Δq, (related to the signal-to-noise ratio, SNR) and finally the reconstruction method. All these parameters were considered to determine the precision and the accuracy of the estimated mechanical moduli and to establish the conditions of validity of MRE following the inversion of the differential equations of the displacement field. In this work, first A and A/ΔA were considered to define a validity threshold for MRE. The influence of A and A/ΔA was studied on a heterogeneous phantom acquired using a 1.5 T MRI with two different types of coils. In a first study, the displacement fields were acquired as a function of A using motion-sensitized spin-echo (REF) and gradient-echo (FFE) sequences for an isotropic spatial resolution of 1 mm. In a second study, the displacement field was acquired as a function of A using RFE for three different spatial resolutions. These studies revealed the existence of a threshold in A/ΔA beyond which the extracted parameters (G', G'') reach a plateau and the MRE is reliable. Then the number of voxels per wavelength, λ/a was considered as a parameter determining the conditions of validity of MRE. This parameter was studied according to the quality of the acquired data characterized by the ratio q//Δq. Simulations were carried in a homogeneous and isotropic elastic medium with a SNR between 5 and 30. The accuracy and the precision of the measurements were found optimal for 6 to 9 voxels per wavelength. The simulation conditions were experimentally reproduced at 2 kHz on a home-made polyvinyl alcohol phantom. The displacement fields were acquired at 11.7 T using a motion-sensitized RFE sequence with spatial resolutions ranging from 150 μm to 300 μm in order to obtain a λ/a ratio ranging from 1 to 20. The experimental results fully confirm the predictions of the simulation. The shear wave velocity decreases with λ/a. It tends towards the expected reference value when the acquisition is performed in the optimal condition, namely here when a is less than or equal to 200 μm. In addition, the standard deviation of the shear wave velocity is reduced for the optimal conditions. Therefore, accurate estimation of mechanical parameters could be deduced. This thesis first demonstrates that the precision and accuracy of MRE are optimal when the acquisitions are performed or processed for a certain wavelength sampling range determined by the SNR. We also showed that for fair comparison of the results, MRE must be carried out in a similar range of q/Δq. Taking into account the conditions of validity of MRE, determined by the ratios λ/a and q/Δq, leads to an effective quantitative measurement of the mechanical parameters making it possible to establish a relevant clinical diagnosis within the same organ, the same subject, between subjects or over time

Texto completoLa tesi presenta l'estensione ed il raffinamento del modello cellulare tridimensionale della crosta e del mantello superiore dell'area centrale mediterranea e propone una interpretazione geodinamica del suddetto modello nel contesto della asimmetria globale della tettonica delle placche. Il modello cellulare è espresso in termini di velocità delle onde di taglio (VS) e di spessore e densità degli strati, fino ad una profondità di 350 chilometri. Tali proprietà caratterizzanti gli strati sono ottenute mediante avanzate tecniche di inversione non lineare, quali l'inversione con il metodo hedgehog di curve di dispersione delle velocità di gruppo e di fase per la determinazione delle VS e l'inversione non lineare di dati gravimetrici mediante il metodo GRAV3D. Il metodo hedgehog consente la definizione di un insieme di modelli strutturali senza fare ricorso ad alcun modello a priori, considerando la VS e lo spessore degli strati come variabili indipendenti. Data la ben nota non unicità del problema inverso, la soluzione rappresentativa di ogni cella è determinata per mezzo dell'applicazione di algoritmi di ottimizzazione ed è inoltre validata alla luce di dati geologici, geofisici e petrologici indipendenti, in particolare la distribuzione della sismicità, sia passata, ottenuta dai bollettini internazionali, sia presente, ottenuta mediante inversione non lineare dei meccanismi focali. Le proprietà delle sorgenti sismiche sono state studiate utilizzando la metodologia INPAR per l'inversione di forme d'onda complete di periodo relativamente corto (fino a 10 s), che permette la determinazione realistica del tensore momento sismico in particolare per eventi poco profondi. Questa metodologia si rivela particolarmente utile nelle aree caratterizzate da eventi di moderata magnitudo, dove le tecniche globali standard non possono in genere venire applicate. Il metodo INPAR fornisce inoltre risultati attendibili anche quando sono disponibili soltanto pochi segnali registrati da un numero limitato di stazioni. L'inversione gravimetrica è stata vincolata alla geometria degli strati definita dal modello VS ottenuto dai dati sismologici. Ai dati gravimetrici di input è applicato un rumore gaussiano con ampiezza di 1,5 mGal. Al fine di non imporre a priori l’esistenza di decrementi della densità al crescere della profondità, il modello di densità di riferimento utilizzato come input dell’inversione consiste, per tutte le celle, in un modello di densità crescente o costante con la profondità, che soddisfa, entro i valori di incertezza, la relazione di Nafe-Drake. Le anomalie ottenute dal processo di inversione gravimetrica vengono poi trasformate in valori assoluti di densità riferiti al modello di riferimento. Il modello tridimensionale così ottenuto, analizzato e discusso lungo sezioni perpendicolari ai complessi orogenetici dell'area di studio (Appennini, Alpi, Dinaridi) conferma l'esistenza di profonde asimmetrie strutturali tra le subduzioni est e ovest-vergenti e la presenza di litosfera sottile nell'area estensiva del bacino Tirrenico, che sovrasta una zona a bassa velocità (LVZ) indicativa della presenza di vaste aree magmatiche o di fusione parziale, probabile sede di un flusso del mantello verso est. Tale flusso è possibile causa dell'asimmetria riscontrata tra la subduzione appenninica, quasi verticale, e la subduzione alpina e dinarica, caratterizzata da un basso angolo di immersione. Ulteriore ed inaspettata caratteristica del modello è rappresentata dal fatto che la litosfera in subduzione risulta essere meno densa del mantello circostante. Tale risultato apre la strada a nuove interpretazioni riguardo alla dinamica delle zone di subduzione, che nella sua descrizione ortodossa vede come fattore determinante il fenomeno dello slab pull. La tesi si articola in un capitolo introduttivo iniziale dove viene esposta l'ipotesi della asimmetria della tettonica delle placche, con particolare riferimento alle evidenze in area mediterranea, mentre nei capitoli successivi vengono presentati i risultati del modello in VS e densità ottenuto a differenti scale risolutive. Tali risultati sono poi discussi, con l'ausilio di sezioni interpretative lungo profili significativi, alla luce di evidenze indipendenti con l'intento di delineare un quadro geodinamico coerente dell'area di studio. In Appendice, unitamente alla presentazione dei risultati tabulati, sono approfondite alcune tematiche particolari.
This thesis presents the extension and refinement of the 3D cellular model of the crust and upper mantle of the central Mediterranean and offers a geodynamic interpretation of the obtained model in the framework of the global asymmetry of plate tectonics. The cellular model is expressed in terms of shear waves velocity (VS), thickness and density of the layers, to a depth of 350 kilometers. These physical properties are obtained by means of advanced non-linear inversion techniques, such as the hedgehog inversion method of group and phase velocity dispersion curves for the determination of VS and the non-linear inversion of gravity data by means of the method GRAV3D. The hedgehog method allows the definition of a set of structural models without resorting to any a priori model, considering the VS and the thickness of the layers as independent variables. Given the well-known non-uniqueness of the inverse problem, the representative solution of each cell is determined through the application of optimization algorithms and is also validated with the use of independent geological, geophysical and petrological data, e.g. the distribution of historical and recent seismicity, obtained from international bulletins and by non-linear inversion of focal mechanisms. The properties of the seismic sources have been studied using the INPAR methodology for the inversion of complete waveforms at relatively short period (as short as 10 s), that allows the determination of the realistic seismic moment tensor in particular for shallow events. This methodology is very useful in areas of moderate magnitude events, where generally the global standard techniques can not be applied. The INPAR method also provides reliable results even using few signals recorded by a limited number of stations. The gravimetric inversion has been constrained to the geometry of the layers defined by the VS model obtained from the inversion of seismological data. A Gaussian noise with an amplitude of 1.5 mGal has been applied to the gravimetric data input. In order not to impose a priori the existence of the density decreases with increasing depth, the reference density model used in the inversion consists, for all the cells, in a model of increasing or at least constant density with depth, which satisfies, within the range of uncertainty, the Nafe-Drake relation. The density anomalies obtained by the gravimetric inversion process are then transformed into absolute values relative to the reference model. The three-dimensional model thus obtained, analysed and discussed along selected sections perpendicular to the orogenic complexes of the study area (Apennines, Alps, Dinarides) confirms the existence of deep structural asymmetries between E- and W-directed subductions and the presence of a thin lithosphere in the extensional area of the Tyrrhenian basin, which overlies a low velocity zone (LVZ) indicative of the presence of large amount of magma or partial melting, where an eastward mantle flow is likely present. This flow possibly causes the asymmetry found between the almost vertical Apenninic subduction and the Alpine-Dinaric subduction, which is in turn characterized by a low dip angle. Further and unexpected feature of the model is the fact that the subducting lithosphere turns out to be less dense than the surrounding mantle. This result opens the way to new interpretations in subductions dynamics, which in its common description relies on the slab pull phenomenon as a first order acting force. The thesis consists of an introduction where the hypothesis of the global asymmetry of plate tectonics is addressed, with particular attention to the Mediterranean context, while in the Chapters 2, 3 and 4 are presented the VS and density models obtained at different resolution scales. These results are then discussed in the Chapter 5, with the aid of interpretive sections along significant profiles, in the light of the validation though independent data, aiming to establish a coherent geodynamic picture of the study area. In the Appendixes, together with the presentation of the tabulated results, some particular topics are discussed.

Texto completoThe application of the standard penetration test (SPT) entails a high level of detail, it is also expensive, requires qualified labor for its execution and is time-consuming; Its use is recommended in sandy soils, restrictive in fine and plastic soils and not recommended in other types of soils. While in the multichannel analysis of surface waves (MASW) its execution is not restricted, it allows covering large areas in short times, however, it is an indirect method, which is why its application must be verified by drilling, obtaining samples, and high analytical criteria. In recent years, the implementation and improvement of soil prospecting techniques has made it possible to carry out studies of the relationship of said tests with different soil parameters. In the present, an empirical correlation was developed between the SPT geotechnical tests by means of the number of penetration resistance blows (N60) with the value of the shear wave velocities (Vs) of the MASW geophysical tests, these tests were carried out in 30 points in the city of Juliaca for sandy soils. There was a final filter of 110 ordered pairs of data (Vs; N60); Through the analysis of potential regression by the method of least squares, the equation was obtained: Vs = 81.079*N600.2646; of the determination coefficient R2:0.76, it was determined that the correlation is acceptable. This equation was put into analysis and comparison with the equations of the correlations of the literature, in which it was found in a trend according to them.
