Introduce your students to the principles and applications of soil dynamics with the leading textbook designed specifically for your introductory course: PRINCIPLES OF SOIL DYNAMICS, 3E. Written by one of today's best-selling authorities on geotechnical engineering, Braja M. Das, and Zhe Luo, Assistant Professor of Civil Engineering at the University of Akron, the latest edition of this well-established text addresses today's most recent developments and refinements in the field. This book focuses primarily on the applications of soil dynamics to prepare your students for success on the job. You will find thorough coverage of the fundamentals of soil dynamics, dynamic soil properties, foundation vibration, soil liquefaction, pile foundation, and slope stability. New discussions, methods, and procedures ensure your students are mastering the latest processes.

  • UP-TO-DATE TREATMENT HIGHLIGHTS THE LATEST PRINCIPLES AND APPLICATIONS RELATED TO SOIL DYNAMICS. Coverage provides the most thorough, contemporary presentation of soil dynamics available in an introductory text, including coverage of machine foundations on piles.
  • BOOK THOROUGHLY INTRODUCES LATERAL EARTH PRESSURE ON RETAINING WALLS. A complete chapter (Chapter 8) on lateral earth pressure on retaining walls gives students a complete introduction to this important topic.
  • COMPLETE UPDATED CHAPTER FOCUSES ON DYNAMIC BEARING CAPACITY OF SHALLOW FOUNDATIONS. The latest coverage reflects updates in this important area of soil dynamics (Chapter 6).
  • APPROACH BALANCES CONCEPTS AND APPLICATIONS. The authors apply their extensive experience to offer a strong balance between the concepts of soil dynamics and their applications within civil engineering today.
