【摘要】 采用ANSYS有限元软件建立某尾矿库坝体的三维有限元模型,然后将该模型导入FLAC3D进行尾矿坝稳定性分析.选取Mohr-Coulomb理想弹塑体本构模型,采用强度折减法并以塑性区贯通为失稳判据计算尾矿坝安全系数.该方法最终得出的尾矿坝安全系数为1.93,与瑞典圆弧法计算结果(1.90)基本一致.更多还原

【Abstract】 A 3D finite element mode of a tailings dam in south China was developed using software ANSYS,which was then introduced into FLAC3 Dto assess the stability of the tailings dam. All constituents in the model were assigned Mohr-Coulomb elastic-perfectly-plastic behavior. Safety factor( SF) was calculated by strength reduction method and using plastic zone connection as failure criteria. The SF value obtained is 1. 94,which is essential in agreement with the result of 1. 90 from Sweden arc method.更多还原
