Preface
The record of the first use of soil as a construction material is lost in antiquity. For years, the
art of soil engineering was based only on past experience. With the growth of science and
technology, the need for better and more economical structural design and construction
became critical. This led to a detailed study of the nature and properties of soil as it relates to
engineering during the early part of the 20th century. The publication of Erdbaumechanik by
Karl Terzaghi in 1926 gave birth to modern soil mechanics. The term geotechnical engineering
is defined as the science and practice of that part of civil engineering which involves natural
materials found close to the surface of the earth. In a general sense it includes the application
of the fundamental principles of soil mechanics and rock mechanics to foundation design
problems.
This handbook on geotechnical engineering is designed for use by geotechnical engineers
and professionals in other civil engineering disciplines as a ready reference. It consists of 15
chapters which cover a wide range of topics including engineering properties of soil, site
investigation, lateral earth pressure, shallow and deep foundations, slope stability, expansive
soil and ground improvement, geosynthetics and environmental geotechnology, railroad base
foundations, and other special foundations. For complete coverage, a chapter on foundation-
soil interactions and a chapter on the vibration of machine foundations also are included. All
the chapters were written by various authors well recognized in their areas of specialty.
As is the case in all handbooks, final equations are presented in the text without detailed
mathematical derivations in many instances. The reader can, however, refer to the references
provided at the end of each chapter for further elaboration.
I sincerely hope that this handbook will be a useful tool for practicing engineers and others
interested in the field of geotechnical engineering.
I am truly grateful to all the authors for their contributions. Thanks also are due to Tim
Pletscher, Senior Acquisitions Editor and Stephen Buda, Vice President for New Business
Development at J. Ross Publishing for their initiative and patience during the development of
this book.
