Abstract:Soil-rock-mixture is widely distributed in nature. Due to its variety in
   component, difference in rock's size and random distribution of rocks,
   the physical and mechanical properties of soil-rock-mixture are very
   complex. In previous studies of stability analysis of soil-rock-mixture
   slope, the slope was usually simplified as homogeneous soil materials
   without considering the influence of rocks. In the present work, the
   shear band of soil and four different kinds of soil-rock-mixture slopes
   under gravity (quasi-static case) and pile driving load (dynamic case)
   are analyzed, respectively. Using the strength reduction method in the
   finite element simulation, the influences of rocks and their spatial
   distributions on the slope stability are discussed. The results show
   that the shear band of soil-rock-mixture slope has obvious rounding rock
   effect, and different locations of rocks have different effects on the
   stability of rock-soil-mixture slope.
