Bearing capacity of strip footings placed on sloping ground
Bearing capacity of strip footings placed on sloping ground
Due to the expansion practices in civil engineering, constructing strip footings near slopes has become a widespread act among engineers. Despite the fact that numerous methods have been conducted to evaluate the bearing capacity of footing adjacent to slopes, the influence of non-associated plasticity has seldom been extensively explored. In this study, a finite difference program has been used to thoroughly investigate numerically the behavior of foundations near slopes using a non-associated flow rule. The bearing capacity factor N which is dependent on soil weight unit was calculated by varying slope angle, setback (b/B) and dilatancy angle with friction angle of 40°. Based on the results, the current study reveals; after a specific distance from the slopes edge, the slope angle has no further impact on the bearing capacity. Additionally, the estimation of the bearing capacity is notably influenced by the dilatancy angle.
