Systematic treatment of difficult ground as a separate paper in undergraduate and postgraduate courses is gaining ground in Indian universities. Earlier, these topics were taught under a variety of subjects like Advanced Geotechnical Engineering, Retaining Structures, Dams, Pavement Designs, Application of Geosynthetics, Application of Soil Mechanics, and so on. However, field requirement and advances in the technology make a strong case for a focused treatment of the subject which this book provides. A full-fledged paper in ground improvement techniques concentrates on the topics of soil stabilization, compaction, preloading, vertical drains, geosynthetics, in-situ reinforcements and modelling of soil reinforcement. The book provides an overview of the basic concepts of ground modifications to difficult soils in a logical and illustrative way. It teaches how to apply alternative solutions to difficult foundation problems and evaluate their effectiveness before and after construction. The text is supported by a large number of examples, review and multiple choice questions, as well as practical problems. The book is intended to serve as a textbook for undergraduate and postgraduate students of Geotechnical, Transportation, Hydraulic and Environmental Engineering, and a reference work for practising civil engineers. Salient features 1. A well researched textbook on ground improvement techniques 2. Conforms to the syllabi of all Indian universities where the subject is taught 3. Written by an expert on the subject with a decade of teaching experience
