ANALYSIS OF MECHANICAL BEHAVIOR OF AN EARTH RETAINING STRUCTURE SUPPORTED WITH GROUND ANCHORS

Abstract

Recent building construction employs often earth retaining structure supported with ground anchors for excavation, for spacious underground facilities. This paper presents a calculation method for the structure of this type. It takes into account the subgrade reaction by the surrounding soil which may act on the wall from non-excavation side, when an additional load is applied to the ground anchors by means of jacks. The non-linear properties of the soil are also considered in this case. Comparison of the theory with experiments on an earth retaining structure with five anchors seated at various depth was satisfactory, proving usefulness of the present method.
