Model studies of bearing capacity of rectangular foundation subjected to eccentric and inclined loads

摘要

This study presents the behaviour of eccentrically inclined loaded rectangular foundation on unreinforced and geogrid reinforced sand carried out experimentally, theoretically and numerically. In the past, several works have been done relating to the estimate of the ultimate bearing capacity (UBC) of shallow foundations supported by geogrid reinforced sand. These researches are limited to strip, square and circular footings. It is found that the less attention was given to determine the UBC of the shallow rectangular foundation under eccentric and inclined load with different depth of embedment D-f. Hence, the present study is based on the behaviour of eccentrically inclined loaded rectangular (surface and embedded) foundation on the unreinforced and geogrid reinforced sand bed. To determine the load-settlement behaviour and compare it with experimental observation, equally theoretical and numerical analysis (PLAXIS 3D) has also been conducted.
