Summary

Summary

Written by authors with years of teaching, research and project experience in reclamation and ground improvement, this book illustrates both theoretical and practical aspects in the design of reclamation and ground improvement works. It covers not only improvement of soft natural soil but also densification of granular fill material. Methods of reclamation, site and equipment selection and construction procedure of shore protection works are also described in this comprehensive book. Additionally, site investigation and characterization required for reclamation and ground improvement projects are explained extensively. This book is an invaluable resource for academics, undergraduate and postgraduate students, researchers and practicing engineers. It is also a useful guide for contractors and consultants who are implementing reclamation and ground improvement projects involving prefabricated vertical drain and deep sand compaction.
