Failure Mode Analysis of Bedding Rock Slope Affected by Rock Mass Structural Plane
Based on the discrete element numerical simulation, the change of failure modes of slope influenced by parameters of rock mass structural plane is studied. It is shown the failure modes shift gradually from the bedding sliding failure modes to the sliding-bending failure modes with the increase of the strength of the rock mass structural plane; The slope failure modes are mainly sliding failure modes with the increasing of the normal and shear stiffness and spacing of rock structural plane. Failure modes shift from shearing slip failure modes to shearing slip and buckling failure modes and finally to the tilting failure modes with the increase of the rock structural plane dip angle. The impact of the rock structural plane cohesion to the slope stability is the greatest, and the stiffness is the least.
