摘要

《水工建筑物抗震设计规范》[1] 所建议的拟静力分析属于毕肖普总应力分析方法，由于没有考虑静态与动态条间孔隙水压力的影响，计算结果偏于不安全。根据渗流场的分析结果得到静态孔隙水压力分布，依据动力液化分析确定动态孔隙水压力增量，并应用于条间水压力分析之中，提出了拟静力分析的改进有效应力分析方法，应用于某一尾矿坝动力稳定分析中得到了较为满意的计算结果。

Abstract

The equivalent static analysis is Bishop’ total stress analytical method

which is recommended by Chinese Specifications for Seismic Design of Hydraulic Structure. Because of thinking no influence of the pore water pressure of inter-slice in static and dynamic state

the calculating results tend to unsafe. It is applied at analysis of pore water pressure of inter-slice which are the static distribution of pore water pressure based on FEM of static seepage field and dynamic pore water pressure increment in the light of dynamic liquefaction FEM analysis. A modified effective analysis method of equivalent static analysis is suggested. The computing result is satisfied in the dynamic stability analysis of a tailings dam.
