摘要
金安桥水电站大坝地震设防烈度高达9度,基岩场地设计水平动峰值加速度为0.399 g,大坝抗震分析和抗震措施设计是工程关键性技术问题之一。采用数值计算法和模型试验法对碾压混凝土大坝进行了全面的动力分析,确定了大坝的抗震薄弱部位,为金安桥水电站大坝设计提供了保证。
The design seismic intensity for Jin＇anqiao RCC gravity dam is up to 9 degree, and the design peak value of horizontal acceleration in the rock base area is 0.399 g. The seismic analysis and design is a key engineering for Jin＇anqiao Project. The comprehensive dynamic analyses are conducted to determine the weak zones in dam by numerical calculation method and model test. The results provide a guarantee to dam design.
