  • HISTORICAL PERSPECTIVE NOW INCLUDES A NEW SECTION ON GEOSYNTHETICS. This foundational chapter details the impact of geotechnical engineering on civil engineering construction with updates and new details of pioneers.

  • NEW MATERIAL DETAILS INFORMATION ABOUT LAVA. In Chapter 2, students now learn important background information about the types and nature of lava from volcanic eruptions, which forms igneous rocks.

  • NEW SUMMARY TABLE COMPARES UNIT WEIGHTS OF SOIL. This helpful new summary table in Chapter 3 presents the various forms of relationships for moist, dry and saturated unit weights of soil.

  • NEW CONTENT DETAILS CASAGRANDE'S PLASTICITY CHART. Students now study Casagrande’s plasticity chart in Chapter 4, as well as empirical data on plasticity limits and indexes from Polidori. The author has added this key information since the ASTM does not provide a test procedure for the shrinkage limit of soil.

  • MANY PLOTS INVOLVING DRY UNIT WEIGHT OF SOIL ARE REPLOTTED IN NON-DIMENSIONAL FORM. Plots in Chapter 6 have been replotted in a non-dimensional form, with new information for obtaining dry density and optimum soil moisture. Students also examine the compaction of organic soil and waste materials.

  • NEW MATERIAL ON SEEPAGE DISCUSSES SIMPLE FLOW PROBLEMS. A new example helps students learn to solve simple flow problems using the equation of continuity. Chapter 8 also now details the procedure for plotting of phreatic line for seepage through earth dams.

  • EXPANDED COVERAGE ESTIMATES VERTICAL STRESS IN SOIL MASS BASED ON NUMEROUS FACTORS.·In Chapter 10 students now learn to estimate vertical stress increase due to horizontal point load, symmetrical vertical triangular strip load, parabolic and conical loading on a flexible circular area.

  • FULL CHAPTER NOW ADDRESSES ELASTIC SETTLEMENT OF SHALLOW FOUNDATIONS. This important information on elastic settlement is now presented in a separate chapter (Ch. 11) with coverage that discusses a sequential theoretical development of elastic settlement relationships and settlement of foundations on saturated clay.

  • NEW COVERAGE EXAMINES SEVERAL METHODS FOR OBTAINING PRE-CONSOLIDATION PRESSURE. New content in Chapter 12 details various procedures for determining pre-consolidation pressure. Students also learn to interpret and use conventional consolidation test results.

  • EXPANDED DISCUSSION EXAMINES NEW TOPICS RELATED TO SHEAR STRENGTH OF SOIL. Chapter 13 provides an overview of the stress path and shear strength of unsaturated soil. Students review correlations for the shear strength parameters of over-consolidated clay. They also review the friction angle of granular soil at critical void ratio state and the effect of the rate of rotation of vane on the magnitude of the undrained cohesion of clay.

  • NEW CONTENT INTRODUCES EXPANDED TOPICS RELATED TO LATERAL EARTH PRESSURE. Chapter 14 now discusses a closed form solution for the active pressure on a retaining wall with a back-fill considering earthquake forces. Chapter 15 also offers a new section on the passive force on walls with seepage.

  • NEW CONTENT ADDRESSES STABILITY OF SATURATED CLAY SLOPES IN EARTHQUAKE FORCES. This new material in Chapter 16 discusses Taylor’s slope stability chart and earthquake effects on soils, provides a case history of slope failure and offers Morgenstern’s method of slices for rapid drawdown condition.

  • NEW THEORIES AND CONTENT PROVIDE ADDITIONAL DETAILS ON SOIL BEARING CAPACITY FOR SHALLOW FOUNDATIONS. New theories, factors and a case history related to bearing capacity of shallow foundations in Chapter 17 better prepares students for future application.

  • NEW CORRELATIONS NOW APPEAR WITHIN THIS EDITION'S DISCUSSION OF SUBSOIL EXPLORATION (CH. 18). Students examine unconfined compression strength, pre-consolidation pressure, and over-consolidation ratio of clay soil.

  • NEW FULL-COLOR INTERIOR DESIGN FEATURES DISTINCTIVE PHOTOGRAPHS OF ROCKS AND ROCK-FORMING MINERALS. These full-colored, detailed images thoroughly capture the unique coloring that helps geotechnical engineers distinguish one mineral or rock from the other.

  • THIS EDITION OFFERS MORE FIGURES AND WORKED-OUT PROBLEMS THAN ANY OTHER SIMILAR TEXT. This edition now offers almost 200 example problems to ensure understanding as well as 275 end-of-chapter practice problems that are updated to reflect the latest developments. This market-leading solution is well known for offering more actual examples and practice than any other of its kind to keep an application-oriented focus on the knowledge your students are acquiring.

  • CHAPTER INTRODUCTIONS AND CLEAR SUMMARIES CLARIFY CONCEPTS. These helpful learning features clearly preview and reinforce content to guide students in their study and assist them in retaining key concepts.
