Abstract

There are many circumstances where shallow footings are constructed near sloping ground. When a footing is placed near the crest of sloping surface, the bearing capacity of the soil and the stability of the slope have been decreased remarkably based on the position of the footing with reference to the slope and slope inclination. In this regard, a sequence of finite element analysis has been carried out using Plaxis 2D v2015.02 to investigate the ultimate bearing capacity of strip footings located near c–φ soil slope. The influence of different geo-parameters on the load carrying capacity of the footing has been investigated, and the outcomes are appropriately explained. Moreover, large database of numerically simulated ultimate bearing capacity has been considered for developing and verifying the ANN model to establish a predictive model equation and the relative importance of the input parameters. It has been professed that angle of internal friction is the most important input parameter for estimating the bearing capacity of strip footing located on crest of c–φ slope.
