平定县大石门水库大坝抗震计算及成果分析

Computing of Earthquake Resistance for Dam of Dashimen Reservoir Pingding County and Its Results Analysis

大石门水库原大坝设计稳定计算未考虑地震荷载。结合工程等级以及其所处地震烈度区域 ,应达设防烈度为 7度 ,为了确保大坝今后运行安全 ,需做抗震安全分析。地震作用效应计算方法采用拟静力法 ,对大坝抗震安全重新进行计算。计算结果表明大石门水库大坝能够抗御

The earthquake load has not been considered in original computing the stability of dam design, Dashimen Reservoir, Pingding County. Therefore in order to ensure the safe operation of the dam, a re-check computation including the earthquake load is made. The result shows that the dam can resist the earthquake intensity of 7 scale, the specified standard.
