Braja M. Das' Sixth Edition of PRINCIPLES OF FOUNDATION ENGINEERING maintainsthe careful balance of current research and practical field applications thathas made it the leading text in foundation engineering courses. Featuring a wealth of worked-out examples and figures that help students with theory and problem-solving skills, the book introduces civil engineering students to the fundamental concepts and application of foundation analysis design. Throughout, Das emphasizes the judgment needed to properly apply the theories and analysisto the evaluation of soils and foundation design as well as the need for field experience. The sixth edition contains many new homework and worked-out problems.
