Additional photographs provide a clearer understanding of the big picture. These new photos added to the book's abundance of illustrations help students understand the material. Most of the photographs are taken from construction sites to provide a clear perspective of real-world challenges. NEW CRITICAL THINKING PROBLEMS APPEAR IN EACH CHAPTER. These problems challenge students to think outside the box and develop creative, workable solutions. NEW COVERAGE HIGHLIGHTS IMPORTANT SKILLS FOR GEOTECHNICAL ENGINEERS. Chapter 4 discusses critical visual identification of soils. Chapter 9 includes a new section on the effects of the initial excess pore water pressures on time-rate consolidation settlement. The average degree of consolidation and corresponding time factor values are given for several initial pore pressure distributions. A new section on construction time correction of consolidation settlement has also been added. BOOK FOCUSES ON CRITICAL CHALLENGES FOR NEW GEOTECHNICAL ENGINEERS. Chapter 10 discusses the selection of the right strength parameters in a project. Chapter 12 includes a new section on field instrumentation, prompted by the increasing use of instrumentation in geotechnical projects. COVERAGE EMPHASIZES NEW KEY TOPICS. Chapter 15 now analyzes cantilever sheet pile walls and anchored sheet pile walls. Chapter 16 discusses bearing capacity of a strip foundation subjected to eccentric and inclined loading in greater detail. Chapter 17 describes a new settlement prediction method for granular soils, proposed by Berardi and Lancellotta, with examples to illustrate its application. The chapter now discusses a simple method to account for the additional settlement of foundations, induced by the water table rise in granular soil. LARGE NUMBER OF SOLVED PROBLEMS APPEAR IN ALL CHAPTERS. Numerous homework problems at the end of each chapter are identified by levels of difficulty. Critical thinking problems at the end of each chapter encourage students to think outside the box. BOOK PROVIDES COMPREHENSIVE TREATMENT OF BOTH SOIL MECHANICS AND FOUNDATION ENGINEERING FOR COMBINED ONE-SEMESTER COURSE. Coverage addresses key topics students need to know, such as slope stability, bearing capacity and settlement of shallow foundations (spread footings and mats), retaining walls, sheet piles, braced cuts, piles, and drilled shafts. HISTORICAL PERSPECTIVE PLACES INFORMATION IN CONTEXT. Book provides detailed background and content development from pre-18th century to present time. REFERENCES PROVIDE ADDITIONAL INFORMATION. Each chapter contains a list of helpful references to assist in further exploration and study. To further prepare students for professional success, all units are presented in SI (Systeme Internationale or International System of Units).
