Soil Liquefaction during Recent Large-Scale Earthquakes contains selected papers presented at the New Zealand – Japan Workshop on Soil Liquefaction during Recent Large-Scale Earthquakes (Auckland, New Zealand, 2-3 December 2013). The 2010-2011 Canterbury earthquakes in New Zealand and the 2011 off the Pacific Coast of Tohoku Earthquake in Japan have caused significant damage to many residential houses due to varying degrees of soil liquefaction over a very wide extent of urban areas unseen in past destructive earthquakes. While soil liquefaction occurred in naturally-sedimented soil formations in Christchurch, most of the areas which liquefied in Tokyo Bay area were reclaimed soil and artificial fill deposits, thus providing researchers with a wide range of soil deposits to characterize soil and site response to large-scale earthquake shaking. Although these earthquakes in New Zealand and Japan caused extensive damage to life and property, they also serve as an opportunity to understand better the response of soil and building foundations to such large-scale earthquake shaking. With the wealth of information obtained in the aftermath of both earthquakes, information-sharing and knowledge-exchange are vital in arriving at liquefaction-proof urban areas in both countries. Data regarding the observed damage to residential houses as well as the lessons learnt are essential for the rebuilding efforts in the coming years and in mitigating buildings located in regions with high liquefaction potential. As part of the MBIE-JSPS collaborative research programme, the Geomechanics Group of the University of Auckland and the Geotechnical Engineering Laboratory of the University of Tokyo co-hosted the workshop to bring together researchers to review the findings and observations from recent large-scale earthquakes related to soil liquefaction and discuss possible measures to mitigate future damage. Soil Liquefaction during Recent Large-Scale Earthquakes will be of great interest to researchers, academics, industry practitioners and other professionals involved in Earthquake Geotechnical Engineering, Foundation Engineering, Earthquake Engineering and Structural Dynamics.

The workshop aims to provide a fundamental understanding of the liquefaction process, necessary to the enhancement of liquefaction prediction. The contributions are divided into eight sections, which include: factors affecting liquefaction susceptibility and field studies of liquefaction.

This publication contains papers presented at the International Workshop on the Physics and Mechanics of Soil Liquefaction, held in Baltimore, Maryland, USA, September 1998. The workshop focused on the physics of liquefaction in order to improve criteria and methods for predicting the collapse of saturated soils, enhance the triggering analysis, develop measures of mitigation, evaluate the effectiveness of remedial techniques and improve the current design recommendations. There are 8 sections entitled: the mechanism of instability ( 4 papers); effect of soil gradation on liquefaction ( 4 papers); factors affecting liquefaction susceptibility ( 5 papers); soil fabric and its effect on liquefaction (3 papers); methods of characterizing liquefaction potential (5 papers); methods of characterizing post-liquefaction deformation ( 3 papers); centrifuge studies of liquefaction ( 3 papers); field studies of liquefaction (3 papers).

Soil liquefaction is a major concern in areas of the world subject to seismic activity or other repeated vibration loads. This book brings together a large body of information on the topic, and presents it within a unified and simple framework. The result is a book which will provide the practising civil engineer with a very sound understanding of soil liquefaction.

Gopal Madabhushi, Jonathan Knappett ... Pile foundations are the most common form of deep foundations that used both onshore and offshore to transfer large superstructure loads into competent soil strata. This book provides many case histories of failure of pile foundations due to earthquake loading and soil liquefaction. Based on the observed case histories, the possible mechanisms of failure of the pile foundations are postulated. The book also deals with the additional loading attracted by piles in liquefiable soils due to lateral spreading of sloping ground. Recent research at Cambridge forms the backbone of this book with the design methodologies being developed directly based on quantified centrifuge test results and numerical analysis. The book provides designers and practicing civil engineers with a sound knowledge of pile behaviour in liquefiable soils and easy-to-use methods to design pile foundations in seismic regions. For graduate students and researchers, it brings together the latest research findings on pile foundations in a way that is relevant to geotechnical practice.

This monograph updates a subject area covered in the 1982 classic text used around the world, Ground Motions and Soil Liquefaction During Earthquakes, by H. Bolton Seed and I.M. Idriss. The new publication will fill a need for a thorough synthesis in one accessible resource for students, practicing engineers, and other professionals of progress in the study of liquefaction since 1982. The following areas are covered: Fundamentals of liquefaction behavior: a framework for a common understanding of the development and limitations of various engineering analytical procedures. Liquefaction triggering analysis: methods for evaluating the potential for liquefaction triggering. Consequences and mitigation of liquefaction: examples of lateral spreading and post-liquefaction settlement analyses, the use of factors of safety in engineering practice, mitigation strategies, and methods for ground improvement. Cyclic softening of saturated clays: engineering procedures for evaluating the potential performance of cohesive fine-grained soils. Three of the 136 figures are in color, illustrating comparisons of liquefaction analysis procedures.

A  Rigorous and Definitive Guide to Soil Liquefaction: Soil liquefaction occurs when soil loses much of its strength or stiffness for a time―usually a few minutes or less―and which may then cause structural failure, financial loss, and even death. It can occur during earthquakes, from static loading, or even from traffic-induced vibration. It occurs worldwide and affects soils ranging from gravels to silts. From Basic Physical Principles to Engineering Practice: Soil Liquefaction has become widely cited. It is built on the principle that liquefaction can, and must, be understood from mechanics. This second edition is developed from this premise in three respects: with the inclusion of silts and sandy silts commonly encountered as mine tailings, by an extensive treatment of cyclic mobility and the cyclic simple shear test, and through coverage from the "element" scale seen in laboratory testing to the evaluation of "boundary value problems" of civil and mining engineering. As a mechanics-based approach is necessarily numerical, detailed derivations are provided for downloadable open-code software (in both Excel/VBA and C++) including code verifications and validations. The "how-to-use" aspects have been expanded as a result of many conversations with other engineers, and these now cover the derivation of soil properties from laboratory testing through to assessing the in situ state by processing the results of cone penetration testing. Downloadable software is supplied on Soil Liquefaction: A Critical State Approach, Second Edition continues to cater to a wide range of readers, from graduate students through to engineering practice.
