运用ABAQUS进行岩质边坡稳定分析

In the elastic-plastic finite element analysis of slope stability, the selection of rock and soil yield criterion is directly impact the slope stability analysis. Considering the same model and geotechnical materials with the same parameters, using ABAQUS finite element software and plastic iterative calculations do not converge as a major slope failure criterion, using Mohr-Coulomb exterior angle point circumcircle model、Mohr - Coulomb interior angle point circumcircle model、 Mohr-Coulomb inscribed circle model、Mohr-Coulomb equal-area circle model and Mohr-Coulomb accurate matches circle model, this paper has studied the rock slope stability model factor of safety. According to compare several methods’ safety factors, discusses the impact of the yield criteria selection to the safety factor.
