摘要: 结合工程实例,采用有限元强度折减法对地震区三维边坡进行静力和拟静力分析,探讨了该方法的基本原理 屈服准则和失稳判据等在采用有限元软件ANSYS求得三维边坡安全系数的基础上,对边坡的稳定性进行了评 价;同时与传统极限平衡方法二维有限元法所得的安全系数进行对比结果表明:有限元强度折减法应用于地震 区三维边坡稳定性分析是可行的

Abstract: Combiningwithengineeringexamples,thestrengthreductionFEMisusedtodostaticandpseudo-staticanalysis onthethree-dimensional slope; thebasicprinciple,yieldcriterion,instabilitycriterionetc. of thestrengthreductionFEM arealsodiscussed. Thesafetyfactorsof thethree-dimensional slopeareobtainedbyuseof thefiniteelement softwareANSYS; furthermore,theslopestabilityisevaluated. At thesametime,thesafetyfactorsgot bytheproposedmethodarecomparedwiththose got by the traditional limit equilibriummethodand2DFEM. The results showthat it is feasible that strengthreductionFEMisappliedinthree-dimensional slopestabilityanalysisof theearthquakezone
