THE LOAD-DEFORMATION CHARACTERISTICS OF ANCHORS IN COHESIONLESS SOIL

Abstract

Horizontal anchors are often used fcr holding back flexible shcoc oil e bulkheads, Their designs are based on either em at rica1 rules or the age-old convensiena1 earth pressure theories. Such, computations lead to uneconomical roSuits. The study of load-deformacirn characteristics of anchorage pl:,.tes buried in crhesienless soil is undertaken in the prosent moos tigeti_n thr ugh is model s"tuly. The problem has been studied as a two-dimensional one on steel anchor pla-tcs 'af f')ur c'iffercnt sizes-2.5, 5.0, 7.5 and 10,0 cm, embedded in the vertical pmsitica Cs different depths in cuhesionless sci.l. The c?epths or embedmenc ranging from 2.5 cm to 75 cm havo been suited. The pull has be-n applied, in the horizontal direction and the behavi.;ur =if ':ho anchor has been studied in tw:! stet--s cf packing namely dense and loos .
