Description
The First Comprehensive Guide to Shallow Foundations
Over the last few decades, the bearing capacity of shallow foundations has been studied more thoroughly than any other subject in geotechnical engineering. Until now, however, most references on foundation engineering devoted only a single chapter to the subject. Shallow Foundations: Bearing Capacity and Settlement provides what many engineers have been waiting for-a concise, comprehensive reference containing all the relevant material on shallow foundation behavior under static and dynamic loads related to their ultimate bearing capacity, allowable bearing capacity, and settlement.
Estimation Techniques, Earthquake Loading, and Experimental Results
The author-a renowned expert-presents the various theories developed during the past fifty years for estimating the ultimate bearing capacity of shallow foundations under various types of loading and subsoil conditions. He discusses the principles of estimating foundation settlement and for estimating the stress increase in a soil mass supporting a foundation. Earthquake loading and its effects on ultimate bearing capacity have received considerable attention in recent years, and the author provides an overview of these developments. He also offers details regarding permanent foundation settlement caused by cyclic and transient loading-details derived from laboratory and field experimental observations.
Progress in Soil Reinforcement
Researchers have made steady progress in evaluating the potential of soil reinforcement to reduce settlement and increase ultimate and allowable bearing capacities of shallow foundations. This book provides an entire chapter on the subject, including discussions of the materials used: galvanized steel strips, geotextile, and geogrid.
The presentation of Shallow Foundations is clear, concise, and filled with examples and exercises that illustrate the theory. This book stands alone as an in-depth, authoritative guide to shallow foundation bearing capacities and the effects of different soil types, slopes, settlement, reinforcement, and seismic activity. Researchers, students, and practicing engineers will all welcome its addition to their reference shelves.
