Random Generation and Stability Analysis of Soil Rock Mixture Slope Model
-
Abstract
This paper focuses on the study of the soil rock mixture slope with different rock contents . Firstly, digital image processing method is used to obtain the digital model of natural rock blocks. Then, based on MATLAB programming, Monte Carlo method is used to randomly generate the slope model of soil rock mixture with specific gradation and rock content. After that, the model is imported into the numerical calculation software FLAC2D and OPTUM G2 respectively, and the finite difference method and finite element limit analysis method are used to calculate the slope. The calculation results are analyzed and show that the plastic zone of homogeneous soil slope is a arc-like sliding zone, while the slip zone of soil-rock mixture slope extends around rocks; and that the mean value of safety factor calculated by FELA method is greater than that calculated by FDM method. -
