Abstract

At present, there are relatively few domestic and foreign studies on the weakening of shear strength of red clay, and the play of residual strength of red clay has not been considered in the study of slope stability. Based on finite element analysis software, this paper carries out the influence of different sliding surface participation coefficients and geometrical forms on the slope stability of red clay slopes considering strength weakening, and the results show that: under the condition of the same water content, the safety coefficient of the slope decreases with the increase of the residual coefficient R; and the safety coefficient of the slope shows the trend of decreasing firstly and then increasing with the increase of the slope gradient i. The research results are important for the proper evaluation of the safety stability of red clay slopes. The research results have important theoretical research significance and engineering practical value for correctly evaluating the safety and stability of slopes.
