The first volume of this series dealt with the Basic Principles of Boundary Elements while the second concentrated on Time-dependent Vibration Problems and volume three on the Computational Aspects of the method. This volume deals with applications of the method to a wide variety of geomechanical problems, most of which are ideally suited for boundary elements and help to demonstrate the potentiality of the technique. The chapters in this volume bring together a series of recent advances made in the applications of BEM for soil mechanics, consolidation, foundations and groundwater flow problems. Research on these problems has progressed to such a degree that the BEM can be employed as an engineering analysis tool.
