Research on Soil-Like Slope Instability Based on FEM Strength Reduction

Abstract:

In the construction of mountainous area roads, the similar soil slope is the most common slope form. During the construction, the problem we often meet is how to make the evaluation about the stability of the similar soil slope. The joints exist in the matrix rock, which make great effect on the stability of the slope. The main idea of this article is to analyze the effect of joints and the rain seeped in on the instability of the slope. To solve the problem, the finite element strength reduction theory is taken in this article, and the geotechnical finite element analysis software z_soil is chosen to make the analysis about the instability criterion and the stability in the condition the rain of the similar slope.
