摘要
在ANSYS有限元软件中,用有限元强度折减法进行边坡稳定分析时,操作比较复杂,且关于岩土材料,ANSYS软件只有一种屈服准则,计算结果偏于安全。首先对二次开发的理论依据进行说明,然后基于ANSYS的二次开发工具APDL和UIDL,对不同的等效DP-MC准则的有限元强度折减法进行二次开发,最后通过标准边坡模型的分析,证明了二次开发程序的合理性和实用性。
When analyzing slope stability by the strength reduction finite element method in ANSYS finite element software, the operation isvery complicated, ANSYS has only one yield criterion about geotechnical materials and the results are on the safety side. This paper firstlydescribed the theoretical basis of the secondary development, then the strength reduction finite element method of the different equivalentDP-MC criteria was secondarily developed based on APDL and UIDL, the secondary development tool of ANSYS. Finally, the standard modelof the slope proved the rationality and practicality of secondary development program.
