Book Description
This book is mainly intended to meet the needs of undergraduate students of Civil Engineering. In preparing the first edition of this book, I had two principal aims: firstly to provide the student with a description of soil behavior-and of the effects of the clay minerals and the soil water on such behavior-which was rather more detailed than is usual in an elementary text, and secondly to encourage him to look critically at the traditional methods of analysis and design. The latter point is important, since all such methods require certain simplifying assumptions without which no solution is generally possible. Serious errors in design are seldom the result of failure to understand the methods as such. They more usually arise from a failure to study and understand the geology of the site, or from attempts to apply analytical methods to problems for which the implicit assumptions make them unsuitable. In the design of foundations and earth structures, more than in most branches of engineering, the engineer must be continually exercising his judgment in making decisions. The analytical methods cannot relieve him of this responsibility but properly used, they should ensure that his judgment is based on sound knowledge and not on blind intuition. I hope that the book will prove to be of use to students when their courses are over, and help to bridge the awkward gap between theory and practice.
