| 摘 要： | 基于强度折减元法，对一段全风化花岗岩路堑边坡进行了稳定性分析。岩土材料本构模型采用Drucker-Prager屈服准则，以等效塑性应变作为判别边坡破坏的判据。通过两种不同边坡设计方案的对比分析表明，强度折减元法在边坡设计中有较强的可靠性和适用性。

| Abstract: | A section of fully-weathered granite cutting slope is analyzed for its stability based on strength reduction finite element method.With Drucker-Prager yield criterion for geotechnical material constitutive model,the equivalent plastic strain is considered as the criterion of slope failure.Through comparison of two slope design programs,it is shown that strength reduction finite element method is highly reliable and applicable in slope design. |
