Soil-rock aggregate slope stability analysis method considering block stone skeleton

The invention belongs to the field of civil engineering, and particularly relates to an earth-rock aggregate slope stability analysis method considering a block stone skeleton, which comprises the following steps: S1, generating a large-particle-size block stone with an initial shape; s2, adjusting the contour of the block stone in the initial shape, and generating the block stone in an irregular shape; s3, randomly putting the generated block stones in a given area according to the set block stone gradation, and establishing contact between the block stones to form a block stone framework; s4, generating small-particle-size block stones to fill skeleton gaps of the large-particle-size block stones, and establishing a soil-rock mixture slope model; s5, dividing finite difference grids, and grouping according to material parameters; and S6, analyzing the earth-rock aggregate slope model according to a finite difference strength reduction method, and generating a slope stability analysis report.
