摘要：Soil-rock mixture is a special engineering geological material,which is
composed of rock with high strength and soil with low strength,whose
mechanical characteristics can be directly investigated by direct shear
tests.In this paper,we adopted spherical elements to represent soil
material,and irregular overlapped clumps to represent the rock rubble
with Discrete Element Model(DEM).The shear strength of soil-rock mixture
was obtained from direct shear tests based on DEM simulation with
different rock contents and inter-element bonding strengths of soil
particles.The results showed that the shear strength of soil-rock
mixture increases with the increase of either the rock content or the
bonding strength.Moreover, the internal friction angle and the cohesive
strength of soil-rock mixture were determined by DEM simulation with
various rock contents.The above results are beneficial to reveal the
shear strength of soil-rock mixture.
