Dynamics Of Soils And Their Engineering Applications

The book offers systematic dynamic analysis of soils and their engineering applications, including machine foundations, and aims to develop a clear understanding of the subject. It comprises sixteen chapters. Chapter 1 introduces the reader to the various problems in soil dynamics. In Chapter 2, concepts of theory of vibrations are discussed along with their applications in designing Vibration Absorbers and Pickups. Wave propagation in elastic medium including wave refraction in layered medium is covered in Chapter 3. Chapter 4 deals with the procedure of determining dynamic properties of soils using various laboratory and field tests. Dynamic earth pressures in retaining walls and dynamic bearing capacity of footings are dealt with in Chapters 5 and 6 respectively. Chapters 7and 8 respectively deal with dynamic behavior of pile foundations and slopes. Causes of liquefaction of soils and prediction of liquefaction potential have been discussed in Chapter 9. In Chapter 10, the procedure of estimating the unbalanced forces in various types of machines are covered. Chapters 11, 12 and 13 deal with the analysis and design of foundations of reciprocating machine, hammer, and turbo-generators respectively. In Chapter 14, problems of vibration isolation and screening are dealt with. Chapter 15 discusses the analysis and design of reinforced earth wall located in seismic areas. A new concept of a conventional rigid retaining wall having reinforced backfill is presented in Chapter 16, giving complete analysis and design procedure considering seismic forces.

Printed on acid-free paper Springer is part of Springer Science+Business Media (www.springer.com) Preface This book gives the material for an introductory course on Soil Dynamics, as given for about 10 years at the Delft University of Technology for students of civil en- neering, and updated continuously since 1994.

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.

The aim of this book is to encourage students to develop an understanding of the fundamentals of soil mechanics. It builds a robust and adaptable framework of ideas to support and accommodate the more complex problems and analytical procedures that confront the practising geotechnical engineer. Soil Mechanics: Concepts and Applications covers the soil mechanics and geotechnical engineering topics typically included in university courses in civil engineering and related subjects. Physical rather than mathematical arguments are used in the core sections wherever possible. New features for the second edition include: an accompanying website containing the lecturers solutions manual; a revised chapter on soil strength and soil behaviour separating the basic and more advanced material to aid understanding; a major new section on shallow foundations subject to combined vertical, horizontal and moment loading; revisions to the material on retaining walls, foundations and filter design to account for new research findings and bring it into line with the design philosophy espoused by EC7. More than 50 worked examples including case histories Learning objectives, key points and example questions

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.

This is perhaps the only book available which may serve as a main reference book for an introductory course on Soil Dynamics. The primary focus of the book is on applications of soil dynamics and not on the underlying principles.

While many introductory texts on soil mechanics are available, most are either lacking in their explanations of soil behavior or provide far too much information without cogent organization. More significantly, few of those texts go beyond memorization of equations and numbers to provide a practical understanding of why and how soil mechanics work. Based on the authors’ more than 25 years of teaching soil mechanics to engineering students, Soil Mechanics Fundamentals presents a comprehensive introduction to soil mechanics, with emphasis on the engineering significance of what soil is, how it behaves, and why it behaves that way. Concise, yet thorough, the text is organized incrementally, with earlier sections serving as the foundation for more advanced topics. Explaining the varied behavior of soils through mathematics, physics and chemistry, the text covers: Engineering behavior of clays Unified and AASHTO soil classification systems Compaction techniques, water flow and effective stress Stress increments in soil mass and settlement problems Mohr’s Circle application to soil mechanics and shear strength Lateral earth pressure and bearing capacity theories Each chapter is accompanied by example and practicing problems that encourage readers to apply learned concepts to applications with a full understanding of soil behavior fundamentals. With this text, engineering professionals as well as students can confidently determine logical and innovative solutions to challenging situations.

Hardbound. 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.
