This book was released on 2024-02-12 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The slope failure is a large deformation problem, the traditional numerical method finite element method (FEM), and limit equilibrium method (LEM) is difficult to characterize the whole process of the failure, resulting in the mechanism analysis which is not clear. In this work, a mesh-free particle approach, named the smoothed particle hydrodynamics (SPH) method, is presented and is improved to analyze the damage and failure process of a rock slope. In order to better describe the cause and mechanism of brittle failure for rock slope, the plastic factor was suggested and introduced into the SPH algorithm, and the conservation equations of SPH for brittleness characteristics were obtained. For soil slope, its instability mechanism and failure mode are different from that of rock slope. Therefore, this work also introduces the application of the smoothed particle hydrodynamics (SPH) method in the instability evolution process of soil slope. Firstly, an improved method for solving the SPH safety factor based on the adaptive discount factor method is proposed, the tolerance value is introduced, the relationship between the displacement increment and the tolerance value of the characteristic point is analyzed, and the real displacement mutation point is determined. Secondly, the SPH numerical model of slope is established to analyze the characteristics of slope deformation and failure, which shows that the SPH method can effectively represent the whole process of slope instability and progressive failure and effectively overcome the disadvantage of non-convergence when the traditional numerical method is used to study the deformation and failure of geotechnical materials.

Download or read book Progressive Failure in Slopes Stability written by Agnese Murianni and published by LAP Lambert Academic Publishing. This book was released on 2011 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the stability analysis of earth slopes the simple computational methods, referred to the classical limit equilibrium approach, are not able to predict complex processes as progressive failure. Such a phenomenon can be studied only using procedures that are able to simulate the formation and development of a shear band in which plastic strains localise. From a computational point of view, this presents many problems, because the numerical analyses, carried out with local elasto-plastic models, are affected by a lack of convergence and the solution depends strongly on the mesh adopted. For this purpose, a non-local elasto-viscoplastic model, implemented in the finite element code TOCHNOG, is proposed in this book. In order to assess the validation of the model, two ideal examples are analysed: a plane strain compression test and a stability analysis of a slope with a given groundwater level. The proposed approach allows to overcome the problems of the local elasto-plastic models and, therefore, it can represent a useful analysis tool of progressive failure for the geotechnical engineers.

Using clear, concise language and practical examples, the book explains the practical aspects of geotechnical engineering as applied to slopes and embankments. The new second edition includes a thorough discussion on the use of analysis software, providing the background to understand what the software is doing, along with several methods of manual analysis that allow readers to verify software results. The book also includes a new case study about Hurricane Katrina failures at 17th Street and London Avenue Canal, plus additional case studies that frame the principles and techniques described. Slope stability is a critical element of geotechnical engineering, involved in virtually every civil engineering project, especially highway development. Soil Strength and Slope Stability fills the gap in industry literature by providing practical information on the subject without including extraneous theory that may distract from the application. This balanced approach provides clear guidance for professionals in the field, while remaining comprehensive enough for use as a graduate-level text. Topics include: Mechanics of soil and limit equilibrium procedures Analyzing slope stability, rapid drawdown, and partial consolidation Safety, reliability, and stability analyses Reinforced slopes, stabilization, and repair The book also describes examples and causes of slope failure and stability conditions for analysis, and includes an appendix of slope stability charts. Given how vital slope stability is to public safety, a comprehensive resource for analysis and practical action is a valuable tool. Soil Strength and Slope Stability is the definitive guide to the subject, proving useful both in the classroom and in the field.

Download or read book Integrated Analysis Method for Stability Analysis and Maintenance of Cut Slope in Urban written by Mincheol Park and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the process of constructing roads for the development of the city, cut-slopes are made by excavating mountains. However, these cut-slopes are degraded in strength by time-deterioration phenomenon, and progressive slope failure is caused. This study developed an integrated analysis method for stability analysis and maintenance of cut-slopes in urban. The slope stability analysis was performed using the finite element model, and the progressive slope failure by time-dependent deterioration was quantified by using the strength parameters of soil applying the strength reduction factor (SRF). The displacements until the slope failure by slope stability analysis were quantified by cumulative displacement curve, velocity curve, and inverse velocity curve and, applied to the slope maintenance method. The inverse-velocity curve applied to the prediction of the time of slope failure was regressed to the 1st linear equation in the brittle material and the 3rd polynomial equation in the ductile material. This is consistent with the proposed formula of Fukuzono and also shows similar behavior to the failure case in literature. In the future, integrated analysis method should be improved through additional research. And it should be applied to cut-slope to prevent disasters.

Available in PDF, EPUB and Kindle. Book excerpt: This practical guide provides the best introduction to large deformation material point method (MPM) simulations for geotechnical engineering. It provides the basic theory, discusses the different numerical features used in large deformation simulations, and presents a number of applications -- providing references, examples and guidance when using MPM for practical applications. MPM covers problems in static and dynamic situations within a common framework. It also opens new frontiers in geotechnical modelling and numerical analysis. It represents a powerful tool for exploring large deformation behaviours of soils, structures and fluids, and their interactions, such as internal and external erosion, and post-liquefaction analysis; for instance the post-failure liquid-like behaviours of landslides, penetration problems such as CPT and pile installation, and scouring problems related to underwater pipelines. In the recent years, MPM has developed enough for its practical use in industry, apart from the increasing interest in the academic world.
