Soil Mechanics and Foundation Engineering has seen unprecedented growth over the last few decades both in terms of knowledge and practice as well as in its significance in civil engineering profession. Over 1300 numerical and objective questions with solutions have been included in the book. Questions from competitive exams such as GATE, IES, IAS, IFS, etc., involve some of the subtle and fine concepts of the subject and their practical application, which cannot be gained by simple reading of the subject. Keeping this in view, about 600 questions from these examinations from a long span of over 25 years (1987 onwards) have been solved in the book.
