SynopsisThe behaviour of the ground on which structures are built during earthquake conditions is crucial to understanding the behaviour of those structures. The properties of soil under dynamic loading are the central theme of this book. Liquefaction of sandy soils and slope failures are particularly studied., The behavior of the ground is crucial to the stability of structures during earthquake conditions. Our understanding of this behavior depends on a knowledge of soil dynamics and the deformation of soils during these catastrophic events. This book provides a comprehensive study of this subject, presenting much of the valuable material accumulated by Japanese researchers over recent years. The author covers theory, laboratory tests, and findings from the field, providing helpful guidance for civil engineers undertaking the critical task of protecting structures in vulnerable zones, This highly topical book, written by a leading Japanese author, provides a comprehensive study of current research in soil dynamics for earthquake engineering. The behaviour of the ground on which structures are built during earthquake conditions is crucial to understanding the behaviour of those structures. This well-illustrated text summarizes current knowledge of the subject, presenting material accumulated by Japanese and other researchers over recent years. It comprehensively covers theory, laboratory tests, and field work. It also includes helpful guidelines for civil engineers undertaking groundwork to protect structures in potential earthquake zones.
