Soil Dynamics And Foundation Modeling

This book presents a comprehensive topical overview on soil dynamics and foundation modeling in offshore and earthquake engineering. The spectrum of topics include, but is not limited to, soil behavior, soil dynamics, earthquake site response analysis, soil liquefactions, as well as the modeling and assessment of shallow and deep foundations. The author provides the reader with both theory and practical applications, and thoroughly links the methodological approaches with engineering applications. The book also contains cutting-edge developments in offshore foundation engineering such as anchor piles, suction piles, pile torsion modeling, soil ageing effects and scour estimation. The target audience primarily comprises research experts and practitioners in the field of offshore engineering, but the book may also be beneficial for graduate students.

Soil dynamics is a moderately new branch of geotechnical engineering that has attracted huge attention in the past two decades or so. Voluminous research publications are the result of exhaustive investigations on the part of researchers in both academia and industry. In the seismic analysis of a structure founded on ground, the ground motion passes to the base of structure and then loads on structure. The response of the foundation system affects the response of the structure and vice versa, which is called dynamical soil-structure interaction. In the seismic resistant design of structures, we are most interested in the strength reduction factors to account for the nonlinear behavior that might be experienced by a structure subjected to an earthquake ground motion. Few researchers have recently attempted to assess the effect of SSI on the strength reduction factors, which is primarily controlled by the changes in the structural period and displacement ductility. This book investigates soil-structure-interaction effects considering nonlinearities occurring at the soil-foundation interface. Soil Dynamics and Foundation Modeling presents a comprehensive new concepts and techniques on soil dynamics and foundation modeling in offshore and earthquake engineering with both theory and realistic applications, and thoroughly links the practical approaches with engineering applications. It contains material pertaining to soil dynamics, earthquake engineering, and special design aspects of geotechnical engineering with basic dynamic properties of soils, machine foundations, dynamic and vibratory compaction, and pile driving response. It also reflects on new findings from research results based on recent case histories. This book will be of valuable for students, researchers, and practicing engineers, interested in this field.

The interaction of soil with structures built in and on the ground is an important field in geotechnical engineering. Its investigation represents a demanding task for the engineer. In the scope of two interdisciplinary research projects in cooperation with a team of international scientists, we investigated experimentally and numerically the behaviour of piles and pile foundations during strong earthquakes. For decades the evolution of soil mechanics was rather separate in statics and dynamics, in particular for the interaction of ground and structure. Even now the latter is often captured in calculations by simplifying assumptions which where never verified, more so in soil dynamics than in statics. Based on the present work this is no more necessary, this can be verified by interested readers up to details. At the end of this publication it is also shown that this new state of knowledge has certainly consequences for design and construction methods.

This book discusses contemporary issues related to soil mechanics and foundation engineering in earthworks, which are critical components in construction projects and often require detailed management techniques and unique solutions to address failures and implement remedial measures. The geotechnical engineering community continues to improve the classical testing techniques for measuring critical properties of soils and rocks, including stress wave-based non-destructive testing methods as well as methods used to improve shallow and deep foundation design. To minimize failure during construction, contemporary issues and related data may reveal useful lessons to improve project management and minimize economic losses. This book focuses on these aspects using appropriate methods in a rather simple manner. It also touches upon many interesting topics in soil mechanics and modern geotechnical engineering practice such as geotechnical earthquake engineering, principals in foundation design, slope stability analysis, modeling in geomechanics, offshore geotechnics, and geotechnical engineering perspective in the preservation of historical buildings and archeological sites. A total of seven chapters are included in the book.

GSP 107 contains 13 papers on soil dynamics and liquefaction presented at sessions of Geo-Denver 2000, held in Denver, Colorado, August 5-8, 2000.

Dynamic Soil-structure interaction is one of the major topics in earthquake engineering and soil dynamics since it is closely related to the safety evaluation of many important engineering projects, such as nuclear power plants, to resist earthquakes. In dealing with the analysis of dynamic soil-structure interactions, one of the most difficult tasks is the modeling of unbounded media. To solve this problem, many numerical methods and techniques have been developed. This book summarizes the most recent developments and applications in the field of dynamic soil-structure interaction, both in China and Switzerland. An excellent book for scientists and engineers in civil engineering, structural engineering, geotechnical engineering and earthquake engineering.

This book gathers selected proceedings of the annual conference of the Indian Geotechnical Society, and covers various aspects of soil dynamics and earthquake geotechnical engineering. The book includes a wide range of studies on seismic response of dams, foundation-soil systems, natural and man-made slopes, reinforced-earth walls, base isolation systems and so on, especially focusing on the soil dynamics and case studies from the Indian subcontinent. The book also includes chapters addressing related issues such as landslide risk assessments, liquefaction mitigation, dynamic analysis of mechanized tunneling, and advanced seismic soil-structure-interaction analysis. Given its breadth of coverage, the book offers a useful guide for researchers and practicing civil engineers alike.

Soil Dynamics and Earthquake Engineering (GSP 201) contains 43 papers which examine a variety of topics in soil dynamics and earthquake engineering. This Geotechnical Special Publication is divided into three groups: the dynamic soil-structural interactions under seismic loads, the dynamic properties of soils and rocks, and seismic zoning and earthquake hazard assessment. These papers cover important issues such as the dynamic responses of earth dams, pile and pile groups, soil nailing, tunnel, landfills and shallow foundations. The papers in this publication were presented during the GeoShanghai 2010 International Conference held in Shanghai, China, June 3-5, 2010.
