本文采用二维有效应力动力分析方法,对山西省册田水库南副坝地基砂层进行了地震液化分析和坝坡动力稳定分析。地震加速度时程曲线,采用了实测和人工合成等三组曲线。从而对该坝的抗震安全性能作出了评价;并对不同地震加速度时程曲线对砂层液化和坝坡稳定的影响作了有益的探讨。
In this paper, seismic liquefaction analysis and dynamic stability analysis of dam slope are carried out by using two-dimensional effective stress dynamic analysis method. Earthquake acceleration time history curve, using the measured and synthetic three sets of curves. The seismic safety performance of the dam is evaluated. The effects of different seismic acceleration curves on sand liquefaction and slope stability are also discussed.
