Building on the success of preceding editions, the Fourth Edition of PRINCIPLES OF FOUNDATION ENGINEERING maintains the careful balance of current research and practical field applications that has made it a leading text in foundation engineering courses throughout the country and internationally. Strengthened with many more worked-out examples and figures to aid student comprehension of theory and practical problem-solving skills, the Fourth Edition features expanded coverage of ultimate and allowable bearing capacity (in Chapters 3 and 4), and new Chapters 6 and 7 on lateral pressure theory and retaining wall design. New field observations have been added to each chapter. Both SI and English units are used throughout.
