- Abstract
In order to study the influence of slope shear strength parameters on its stability and reliability,a stochastic response surface analysis model of slope reliability based on Hermite polynomial expansion is established, and the influence of the correlation of shear strength parameters on slope safety coefficient and standard deviation and stability failure probability is studied. The results show that the stochastic response surface method can significantly improve the computational efficiency and ensure the accuracy of calculation compared with that of MCS. The correlation of shear strength parameters of different strata has little influence on the mean value of slope safety coefficient, and the influence on the standard deviation of slope safety coefficient and failure probability is significantly different, and the overall trend is downward with the increase of correlation.
