Soft Clay Engineering and Ground Improvement covers the design and implementation of ground improvement techniques as applicable to soft clays. This particular subject poses major geotechnical challenges in civil engineering. Not only civil engineers, but planners, architects, consultants and contractors are now aware what soft soils are and the risks associated with development of such areas.

The book is designed as a reference and useful tool for those in the industry, both to consultants and contractors. It also benefits researchers and academics working on ground improvement of soft soils, and serves as an excellent overview for postgraduates. University lecturers are beginning to incorporate more ground improvement topics into their curricula, and this text would be ideal for short courses for practicing engineers. It includes several examples to assist a newcomer to carry out preliminary designs.

The three authors, each with dozens of years of experience, have witnessed and participated in the rapid evolvement of ground improvement in soft soils. In addition, top-tier professionals who deal with soft clays and ground improvement on a daily basis have contributed, providing their expertise in dealing with real-world problems and practical solutions.

This book offers a simple seepage solution method for practising geotechnical engineers. It outlines the background and fundamentals of seepage analysis, covers the method of fragments (MoF) for problems in the Cartesian plane, and extends this from plane flow to axisymmetric problems.

Permeability principles and laboratory and empirical methods for determination of permeability are set out, followed by flow nets in both isotropic and anisotropic cases, seepage force, and critical hydraulic gradient. MoF solutions for double-walled and axisymmetric cofferdams are then presented, and guidance is given on the implementation of the MoF in a spreadsheet for determining flow rates and exit hydraulic gradients. Further, simple seepage solutions are presented for three-dimensional flow scenarios associated with square and rectangular cofferdams, as well as selected underground engineering applications, such as underground mine stopes. The findings have been validated extensively using numerical models and laboratory models.

This book suits practising engineers, hydrologists, and researchers needing simple methods to compute flow rates and exit hydraulic gradients in seepage problems, especially cofferdams.

This book presents a one-stop reference to the empirical correlations used extensively in geotechnical engineering. Empirical correlations play a key role in geotechnical engineering designs and analysis. Laboratory and in situ testing of soils can add significant cost to a civil engineering project. By using appropriate empirical correlations, it is possible to derive many design parameters, thus limiting our reliance on these soil tests. The authors have decades of experience in geotechnical engineering, as professional engineers or researchers. The objective of this book is to present a critical evaluation of a wide range of empirical correlations reported in the literature, along with typical values of soil parameters, in the light of their experience and knowledge. This book will be a one-stop-shop for the practising professionals, geotechnical researchers and academics looking for specific correlations for estimating certain geotechnical parameters. The empirical correlations in the forms of equations and charts and typical values are collated from extensive literature review, and from the authors'' database.
