Anchors are primarily used in the construction of foundations of earth-supported and earth-retaining structures. The anchors are used in construction to transmit the outwardly-directed load to soil at a greater depth and/or farther from the structure. Although earth anchors 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 twenty years or so. This book summarizes most of the theoretical and experimental works directed toward the ultimate and allowable holding capacity of earth anchors. The book contains six chapters with detailed discussions on horizontal, vertical and inclined anchor plates, helical anchors, and anchor piles. Discussions on the failure mechanism in soil located around the anchor, as well as various theories to calculate the ultimate and allowable loads, are presented. Laboratory and field test results which are required to supplement and verify the theories have also been included. This book is of interest to consulting engineers in geotechnical engineering, as well as geotechnical engineering researchers and engineering libraries.
