LOAD TRANSFER OF PILES IN SAND ADJACENT TO A SLOPE

Abstract

An experimental testing program was designed to study the behavior of a laterally loaded single pile and pile groups adjacent to ground slope. The effect of the ground slope adjacent to the pile was studied by different factors such as the distance of the pile head from the crest of the slope, the slope gradient, and the length to the diameter ratio of the pile. Piles were tested at different sand densities and ground slopes. Improving the lateral response for piles adjacent to ground slope is described by three basic methods: pile head enlargement, compaction of top layer, and using batter piles. Also, tests were conducted

on fixed head 2xl and 2x3 pile groups at three diameter (3D) spacing. The effect of piles arrangement in the group are studied. A three-dimensional elasto-plastic theoretical model based on COSMOS/M finite elements program code (Ver: 2.6, 2000) is proposed to study the problem. Statistic study for the results of the research was achieved by using statistical software called (SPSS).
