在ABAQUS软件提供的线性Drucker-Prager模型和场变量的基础上,结合Mohr-Cou-lomb内切圆屈服准则在ABAQUS中的参数转换公式,对边坡进行稳定性计算。依据弹塑性有限元计算中边坡的各种失稳判据对Mohr-Coulomb屈服准则以及Mohr-Coulomb内切圆屈服准则在边坡稳定分析中的适用性进行了探讨,同时对边坡的失稳判据结果进行了对比分析,鉴于在工程应用中的适用性,当采用强度折减弹塑性有限元法进行计算时,宜联合采用位移判据和塑性区判据对边坡的稳定性进行分析。

On the basis of linear Drucker-Prager model and field variables provided by the software ABAQUS,we combine witla parameters transformation formula related the inscribed circle in the Mohr-Coulomb yield criterion, and calculate the slope stability. According to the elasticlastic finite element calculation of slope instability criteron,we discuss and analyze the applicability of the Mohr-Coulomb yield criterion and the inscribed circle in the Mohroulomb yield criterion in slope stability in this paper. At the same time, we make an comparison to the results of slope instability criterion. In light of the applicability in engineering applications,when the elastic-plastic finite element method of strength reduction is employed, it is better to adopt an combined analysis of displacement criterion with the plastic zone criterion to analyze the stability of the slope.
