Finite Element Analysis of Failure Characteristics of Structural Soil Slope under Different Rainfall Patterns

论文摘要

The slope model is established by Geo-Studio, and the deformation characteristics and stability of structural-soil slope in Zhanjiang area under different rainfall patterns are analyzed. The MK model was used basing on Morgenstern-price method. By setting monitoring points at the top, toe and slope surface of the slope, the variation rule of pore water pressure and displacement at the monitoring points under the four types of rainfall are gotten, and the shapes of different types of sliding surfaces are obtained. By the analysis of the most dangerous sliding surfaces, some suggestions are put forward. Those have important reference value for prevention or controlling the geological disasters such as landslides in Zhanjiang area.
