The book Soil Mechanics has been developed as a text book for the students of Civil Engineering. The sequence of chapters presented is in accordance with UGC approved curriculum for Civil Engineering degree. Fundamentals on soil mechanics are explained in the simplest manner with lot of example problems. At the end of each chapter problems and descriptive questions are added to be solved by students. Numerous illustrative diagrams, tables, charts, photographs and graphs have been presented in this book for better explanation of topics. This book is the outcome of authors experiences gained while teaching the subject as well as in the practical field where the application of knowledge in soil mechanics are applied. As such its preparation is to meet the needs of engineering education and profession of Civil Engineers. This book is designed for use as a text book to the students pursuing engineering and technical education in Engineering Universities, Engineering Colleges, Polytechnic Institutes and other Technical Institutions. The authors hope that the book will certainly be liked by the students, teachers as well as the practicing engineers. A large number of books and journals have been consulted and used in preparing this book. Effort is made to acknowledge the source of information and if any omission is committed that is not intentional.
