Abstract EN
The soil-rock mixture is a cohesive-frictional geomaterial subjected to impacts of composition and structure seriously.
When it suffers from gravity or other kinds of loadings, the loss of its bearing capacity always appears a progressive failure.
In this study, the ultimate criterion of the frictional material changing from the deformation stage to the failure stage is analyzed first and then the deformation and failure characteristics of the soil-rock mixture with different compositions and structures are discussed by the discrete element method.
The results indicate that the deformation and failure of the soil-rock mixture under axial pressure appear a significant phenomenon of detouring around rock blocks.
The bond failure zones and the ultimate shear strain increase with the increase of rock block proportion.
The distribution of the bond failure zones always has a good uniformity with the inclination of rock block inclinations.
The increase of cementation degree between particles expands the distribution of the bond failure zones but minifies the ultimate shear strain.
