摘要
利用ANSYS参数化设计语言(APDL)建立边坡模型,采用Visual Basic语言编写ANSYS-ABAQUS接口程序,实现ABAQUS模型的自动、快速生成。在岩土方面,ABAQUS提供丰富的材料本构模型,利用有限元强度折减法与ABAQUS中的Mohr-Coulomb准则相结合,通过对边坡的稳定性分析,不仅得到了边坡的稳定系数、预测了边坡的潜在滑裂面的位置.同时讨论了Mohr-Coulomb准则参数的影响。为快速有效地分析边坡稳定问题提供了一种思路。
Using ANSYS parameter design language （APDL）to create slope model,and the interface programm of ANSYS-ABAQUS is complied with visual basic language. In this way, the model can create automatically in ABAQUS. In the application of geologic engineering,ABAQUS has an abundance of constitute. In this paper,the strength reduction FEM has been combined with the Mohr-Coulomb yeild criteria in ABAQUS. Through numericalAnalysis of the slope , it can not only get the safty factor of the slope,but also can excatly predict the corresponding shape and position of the potential slipsurface. In the meanwhile,the influence of parameters of the Mohr-Coulomb yeild criteria was discussed as well. The method proposed in this paper provisdes a way of solving the stablility of the slope quickly and efficiently.
