Abstract

The bearing capacity of slope foundation is an important condition for the stability of mountain transmission line. At present, the methods for studying the bearing capacity of slope foundation are mainly as follows, such as the Limit Analysis Method, Slip-Line Field Method and Numerical Simulation Method. In this paper, the numerical simulation method with high accuracy is used to study the bearing capacity changes of slope foundation under different slope ratios, slope border margin and foundation conditions with the help of the finite difference software FLAC3D. Based on the correlations obtained from above, the reasons and laws for the changes of the ultimate foundation bearing capacity can be found, which can provide some guidance for related engineering design.
