Earth anchors / by Braja M. Das and Sanjay Kumar Shukla. — Second edition.Anchors are primarily used in the construction of foundations for earth-sup-
ported and earth retaining structures. The fundamental reason for using earth
anchors in construction is to transmit the outwardly directed load to the soil
at a greater depth and or farther away from the structure. Although earth an-
chors have been used in practice for several hundred years, proper theoretical
developments for purposes of modern engineering design have taken place only
during the past 40 to 45 years or so. This book summarizes most theoretical and
experimental works related to the development of proper relationships for ul-
timate and allowable holding capacities of earth anchors.
The first edition of this book was published with a 1990 copyright by Elsevier
Science Publishers B.V., Amsterdam, The Netherlands, in the Developments in
Geotechnical Engineering Series (No. 50). It was reprinted with a 2007 copyright
by J. Ross Publishing in their Classics Series. Sanjay Kumar Shukla is the co-
author of this second edition. The book now has a total of ten chapters. In this
edition, the following major changes have been made:
• Horizontal plate anchors in sand are presented in Chapter 2 and hori-
zontal plate anchors in clay in Chapter 3.
• Helical anchors are now presented in two chapters: anchors in sand in
Chapter 6 and anchors in clay in Chapter 7. A discussion on single-helix
screw anchors in sand has been added to Chapter 6.
• Two new chapters have been added: suction and caisson anchors (Chap-
ter 9) and geo-anchors (Chapter 10).
• A summary section has been included for each chapter.
• Self-assessment multiple-choice questions, followed by answers, are given
at the end of each chapter.
