- In Chapter 1 on Geotechnical Properties of Soil, new sections on liquidity index and activity have been added. The discussions on hydraulic conductivity of clay, relative density, and the friction angle of granular soils have been expanded.
- Expanded treatment of the weathering process of rocks is given in Chapter 2, Natural Soil Deposits and Subsoil Exploration In Chapter 3 (Shallow Foundations: Ultimate Bearing Capacity), a new case study on bearing capacity failure in soft saturated clay has been added. Also included is the reduction factor method for estimating the ultimate bearing capacity of eccentrically loaded strip foundations on granular soil.
- Chapter 4, Ultimate Bearing Capacity of Shallow Foundations: Special Cases, has new sections on the ultimate bearing capacity of weaker soil underlain by a stronger soil, the seismic bearing capacity of foundations at the edge of a granular slope, foundations on rocks, and the stress characteristics solution for foundations located on the top of granular slopes.
- Stress distribution due to a point load and uniformly loaded circular and rectangular areas located on the surface of a Westergaard-type material has been added to Chapter 5 on Allowable Bearing Capacity and Settlement. Also included in this chapter is the procedure to estimate foundation settlement based on Pressuremeter test results.
- Lateral earth pressure due to a surcharge on unyielding retaining structures is now included in Chapter 7 (Lateral Earth Pressure). Also included in this chapter is the solution for passive earth pressure on a retaining wall with inclined back face and horizontal granular backfill using the method of triangular slices.
- Chapter 8 on Retaining Walls has a new case study. A more detailed discussion is provided on the design procedure for geogrid-reinforced retaining walls.
- Chapter 9 on Sheet Pile Walls has an added section on the holding capacity of plate anchors based on the stress characteristics solution.
- Two case studies have been added to the chapter on Braced Cuts (Chapter 10). • The chapter on Pile Foundations (Chapter 11) has been thoroughly reorganized for better understanding.
- Based on recent publications, new recommendations have been made to estimate the load-bearing capacity of drilled shafts extending to rock (Chapter 12).
