Abstract

Research purposes： In this paper, a new method for analyzing loess slope stability is proposed, with which the vertical joints character of loess can be calculated. Using ABAQUS software and finite element method, the analysis of the loess slope is made through numerical simulation，and the calculation is made on the parameters of the joints and crack inner of rock or soil in the course of stability analysis of loess slope.

Research conclusions ：This paper utilizes the finite element method to analysis the stability of loess slope, which can consider the vertical joints of loess slope. Compared with limit equilibrium method, the finite element method is much better in analysis of loess slope stability. The calculation example shows that the joint material model in ABAQUS is suitable for loess slope and ABAQUS finite element software applies to the study on stability of loess slope.
