心墙风化料坝坝坡稳定计算与分析

Stability Calculation and Analysis of Dam Slope of Core Wall Weathered Material Dam

计算分析的目的是通过采用不同计算方法对金场坝水库黏土心墙风化料坝的数值模拟计算,研究大坝坝坡稳定,并根据计算结果显示暴露出的问题,以指导大坝后期施工。金场坝水库粘土心墙风化料坝属于四级建筑物,根据规范,在地震工况下坝坡抗滑稳定最小安全系数为1.10。依据坝坡稳定分析计算可知,其最小安全系数为1.124,均大于规范要求,所以在Ⅷ度地震作用下是安全的。

In this paper,different calculation methods are used to simulate the values of weathered material dam of clay core wall of Jinchangba Reservoir to study the stability of dam slope.The exposed problems are shown according to the calculation results to guide the later construction of the dam.The weathered material dam of clay core wall of Jinchangba Reservoir belongs to the fourth-class structure.According to the code,the minimum safety factor for stability against sliding of dam slope under seismic conditions is 1.10.According to the stability analysis and calculation of dam slope,the minimum safety factor is 1.124,which is greater than the specification,so it is safe under the action ofⅧdegree earthquake.
