Anchors are primarily used in the construction of foundations of
earth-supported 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 anchors have been used in practice for
several hundred years, proper theoretical developments for purposes of
modern engineering designs have taken place only during the past 40 to
45 years. This geotechnical engineering book summarizes most theoretical
and experimental works directed toward the development of proper
relationships for ultimate and allowable holding capacity of earth
anchors.
