Integration Algorithms Based on Drucker-Prager Criterion and Application in Slope Stability Analysis

摘要：

　　In this paper,an incremental analysis method of perfect elasto-plastic constitutive relation based on Drucker-Prager criteria is adopted in nonlinear finite element computation,which is of first-order accuracy and unconditional stable.This method converges for either small load steps or large load steps.The method was embedded into a 3D nonlinear FEM software named TFINE and applied to stability analysis of Dagangshan high slope.Both theoretical analysis and numerical example show that the method is suitable for limit analysis and can achieve high accuracy to large load increment.
