Bedding Slope Stability and Progressive Failure Analysis

This article based on strain-softening and rigid body limit equilibrium principle, consider the strain softening of slip surface during the analysis, thus in the condition of considering the peak strength and residual strength of slip surface soil strength established bedding slope ideal plane slope body mechanical model and deduced safety factor of bedding slope that occurred traction failure calculation formula. And using the contact element model that in the finite difference method FLAC3D software to simulate the sliding surface and joint of the bedding slope(slow dip angle), show the shear band of slope progressive formation process and analysis the stress characteristics of surface, thus, the failure of the bedding slope is a gradual process, which is gradually expanded through local failure.
