SOIL MECHANICS- Arnold Verruijt

SOIL MECHANICS

Arnold Verruijt

PREFACE

  This book is the text for the introductory course of Soil Mechanics in the Department of Civil Engineering of the Delft University of Technology,as I have given from 1980 until my retirement in 2002. It contains an introduction into the major principles and methods of soil mechanics, suchas the analysis of stresses, deformations, and stability. The most important methods of determining soil parameters, in the laboratory and insitu, are also described. Some basic principles of applied mechanics that are frequently used are presented in Appendices. 

  The subdivision intochapters is such that one chapter can be treated in a single lecture, approximately.Comments of students and other users on the material in earlier versions of this book have been implemented in the present version, anderrors have been corrected. Remaining errors are the author’s responsibility, of course, and all comments will be appreciated.

  An important contribution to the production of the printed edition, and to this screen edition, has been the typesetting program TEX, by Donald Knuth, in the LATEXimplementation by Leslie Lamport. Most of the figures have been constructed in LATEX, using the PICTEX macros.The logo was produced by Professor G. de Josselin de Jong, who played an important role in developing soil mechanics as a branch of science,and who taught me soil mechanics.

   Since 2001 the English version of this book has been made available on the internet, on the website<http://geo.verruijt.net>. Several users,from all over the world, have been kind enough to send me their comments or their suggestions for corrections or improvements. In recentversions of the screenbook it has also been attempted to incorporate the figures better into the text, using the macro wrapfigure, and colors. Inthis way the appearance of many pages seems to have been improved.
