Stability Analysis Of Slope Based On Green-Ampt Model Under Heavy Rainfall, Yong-Hua Su, Cheng-Cheng Li
Rock and Soil Mechanics
The method of rainfall infiltration analysis directly affects the prediction and prevention of rainfall-induced landslides. Green-Ampt (GA) model, which has clear physical meaning and few parameters, has been paid more and more attention in the analysis of rainfall-induced landslides. However, this method ignores the existence of the unsaturated layer of the wetting layer and the seepage of the saturated layer, which affects the calculation accuracy. In view of the above deficiencies, the LSGA model is established based on the stratified hypothesis and the saturated layer seepage, and the expression of slope stability coefficient is established. All results show that LSGA …

A Study Of Water Content Distribution And Shallow Stability Of Earth Slopes Subject To Rainfall Infiltration, Zhen-Ning Shi, Shuang-Xing Qi, Hong-Yuan Fu, Ling Zeng, Zhong-Ming He, Rui-Min Fang
Rock and Soil Mechanics
A rainfall infiltration test model which enables the measurement of the volumetric water content of soil is designed. The distribution and variation of the initial water content under rainfall infiltration are obtained through the test. Based on these results, a novel method for shallow stability analysis of earth slopes subject to rainfall infiltration is proposed by combining the unsaturated shear strength theory and the limit equilibrium method. The proposed method is then applied to study the stability of a soil slope along the Qili connecting line of Hang-Xin-Jing Expressway. The main findings are as follows: The inverse proportion function characterized …
