Intended as an introductory text in soil mechanics, the eighth edition of Das, PRINCIPLES OF GEOTECHNICAL ENGINEERING offers an overview of soil properties and mechanics together with coverage of field practices and basic engineering procedure. Background information needed to support study in later design-oriented courses or in professional practice is provided through a wealth of comprehensive discussions, detailed explanations, and more figures and worked out problems than any other text in the market.

Features:

• Includes a comprehensive discussion on weathering of rocks and the formation of sedimentary and metamorphic rocks.
• Presents a detailed explanation for the variation of the maximum and minimum void ratios of granular soils due to grain size, shape, and non plastic fine contents.
• The Kozeny-Carman equation and modifications thereof to estimate hydraulic conductivity of granular soils is discussed in detail.
• More figures and worked out problems than any other text in the market.
• The most recent information and findings in the literature.
• Case histories have been added in appropriate chapters in order to familiarize the student with the unpredictable variability of soil in the field.
• Challenging critical thinking problems have been added to the end-of-chapter problem sections for increased understanding of the content.
• A 16-page color insert of photographs including rocks and rock-forming minerals has been added to this edition in order to fully capture the unique coloring that helps geotechnical engineers distinguish one mineral/rock from the other.
• Chapter introductions and summaries have been expanded in this edition in order to more clearly lay out the content, both before and after it's been read.

Braja M. Das Dr. Braja Das is Dean Emeritus of the College of Engineering and Computer Science at California State University, Sacramento. He received his M.S. in Civil Engineering from the University of Iowa and his Ph.D. in the area of Geotechnical Engineering from the University of Wisconsin. He is the author of several geotechnical engineering texts and reference books and has authored more than 250 technical papers in the area of geotechnical engineering. His primary areas of research include shallow foundations, earth anchors, and geosynthetics. He is a Fellow and Life Member of the American Society of Civil Engineers, Life Member of the American Society for Engineering Education, and an Emeritus Member of the Chemical and Mechanical Stabilization Committee of the Transportation Research Board of the National Research Council (Washington D.C.). Dr. Das has received numerous awards for teaching excellence, including the AMOCO Foundation Award, AT&T Award for Teaching Excellence from the American Society for Engineering Education, the Ralph Teetor Award from the Society of Automotive Engineers, and the Distinguished Achievement Award for Teaching Excellence from the University of Texas at El Paso. Khaled Sobhan Khaled Sobhan is an Associate Professor of Civil Engineering at Florida Atlantic University. He received his M.S. degree from The Johns Hopkins University, and his Ph.D. from Northwestern University, both in the area of Geotechnical Engineering. His primary research areas include ground improvement, geotechnology of soft soils, experimental soil mechanics, and geotechnical aspects of pavement engineering. He served as the Chair of the Chemical and Mechanical Stabilization committee (AFS90) of the Transportation Research Board (2005-2011), and co-authored the TRB Circular titled Evaluation of Chemical Stabilizers: State-of-the-Practice Report (EC086). He is currently serving as an Associate Editor of ASCE Journal of Materials in Civil Engineering, and on the editorial boards of the The ASTM Geotechnical Testing Journal, Geotechnical and Geological Engineering (Springer, The Netherlands), and International Journal of Geotechnical Engineering. He is a recipient of the distinguished Award for Excellence and Innovation in Undergraduate Teaching (2006), and the Excellence in Graduate Mentoring Award (2009) from Florida Atlantic University. He has published more than 75 technical articles and reports in the area of geotechnical engineering.
