Zusatztext "...The only book that deals with the degradation of ballast under both static and dynamic loads..." Robert L Smith (Australian Geomechanics! vol 40! December 2005) Informationen zum Autor Prof. Buddhima Indraratna is Professor of Civil Engineering at University of Wollongong! Wollongong City! Australia. He has been the team leader of a number of Railway Geotechnology research projects in Australia funded by the Australian Research Council and the Cooperative Research Centre for Railway Engineering in Australia. Dr. Wadud Salim is a Research Engineer at University of Wollongong. He has been working on railway geotechnology for the last 4-5 years. His special interest includes behaviour of railway ballast under cyclic loading. His research projects were sponsored by the Australian Research Council and Cooperative Research Centre for Railway Engineering! Australia. . Klappentext Presents the triaxial testing of ballast including the strength! deformation and degradation aspects of fresh and recycled ballast under monotonic and cyclic loading. The effectiveness of geosynthetics in stabilising recycled ballast is examined. A stress-strain constitutive model for ballast incorporating particle breakage is presented. Zusammenfassung The strength, deformation and degradation behaviour of ballast and the effectiveness of geosynthetics in stabilising recycled ballast have been described in this book. Relevant experimental procedures and theoretical aspects are discussed, and a new stress-strain constitutive model for ballast is proposed. Inhaltsverzeichnis 1. Introduction 2.
