BEHAVIOR OF TEMPORARY ANCHORS IN SELTY SAND SOILS

Using grouted soil anchors has a comparatively recent development in the few past decades. They have become an increasingly used economic and reliable construction technique. The Egyptian geotechnical code 2001, however, does not address or deal with the design and the construction of ground anchor in details. The behavior of temporary ground soil anchors is introduced in this paper through investigating their response under full-scale tension tests. Two case histories are presented herein to illustrate the behavior of temporary anchors in silty sand formations of Egyptian soils. Furthermore, an extensive comparison study is performed between the results of numerical model using finite element method and those of in-situ load-displacement tests showing the adequacy of the proposed numerical scheme. In addition, the research investigates the influence of existence of fine soil contents on the number of failed anchors during pullout tests.
