| 摘 要： | 采用有效应力动力分析方法,结合抗液化剪应力法基本理论和地震永久变形理论,运用大型岩土分析软件Geo-Studio,对某典型上游法尾矿高堆坝进行了地震动力分析,计算出了在8度地震作用下尾矿堆积坝的液化范围和永久变形,并给出了相应的加固措施,为该尾矿坝在高烈度地震区的设计及管理提供参考,同时可为类似工程提供借鉴。

| Abstract: | On the Theoretical base of anti-liquefaction shear stress and seismic permanent information, using dynamic effective stress analysis methods, this article carried out seismic dynamic analysis of a typical uplift tailings dam ,with the large-scale geotechnical analysis software Geo-Studio. The key data calculated includes the area of liquefaction and permanent deformation of the tailings dam ,when 8-degree earthquake occurred. The paper can be a reference for similar projects. |
