Fundamentals of Soil Mechanics for Sedimentary and Residual Soils

Informationen zum Autor LAURENCE D. WESLEY has worked as a practicing geotechnical engineer for over thirty years, and his professional experience encompasses projects in New Zealand, Australia, Indonesia, Malaysia, and Bahrain. A member of American Society of Civil Engineers, he is a recently retired senior lecturer in geotechnical engineering at the University of Auckland. Klappentext Introducing the first integrated coverage of sedimentary and residual soil engineeringDespite its prevalence in under-developed parts of the United States and most tropical and sub-tropical countries, residual soil is often characterized as a mere extension of conventional soil mechanics in many textbooks. Now, with the rapid growth of construction in these regions, it is essential to gain a fuller understanding of residual soils and their properties-one that's based on an integrated approach to the study of residual and sedimentary soils. One text puts this understanding well within reach: Fundamentals of Soil Mechanics for Sedimentary and Residual Soils.The first resource to provide equal treatment of both residual and sedimentary soils and their unique engineering properties, this skill-building guide offers:* A concise introduction to basic soil mechanics, stress-strain behavior, testing, and design* In-depth coverage that spans the full scope of soil engineering, from bearing capacity and foundation design to the stability of slopes* A focus on concepts and principles rather than methods, helping you avoid idealized versions of soil behavior and maintain a design approach that is consistent with real soils of the natural world* An abundance of worked problems throughout, demonstrating in some cases that conventional design techniques applicable to sedimentary soils are not valid for residual soils* Numerous end-of-chapter exercises supported by an online solutions manual* Full chapter-ending referencesTaken together, Fundamentals of Soil Mechanics for Sedimentary and Residual Soils is a comprehensive, balanced soil engineering sourcebook that will prove indispensable for practitioners and students in civil engineering, geotechnical engineering, structural engineering, and geology. Zusammenfassung Given the predominence of residual soils in the under-developed parts of the United States and the Southern Hemisphere, and the increasing rate of new construction in these regions, the understanding of residual soils is expected to increase in importance in the coming years.
