摘要

针对金安桥水电站左岸坡坝段群设防烈度高、坝基构造复杂和坝体横缝结构特殊的特点,对横缝进行了一系列合理的简化并应用动力分析方法对左岸坡坝段群进行了抗震性能分析。分析结果表明:金安桥水电站左岸坡坝段群在9度地震作用下,坝踵、坝趾处的抗拉、抗压强度和单个坝段、坝段群的抗震稳定性均满足现行抗震规范要求,说明金安桥水电站大坝设计合理,能够抵御设防地震。
Under consideration of the high design seismic intensity, complicated structure of the dam foundation and the special structure of the transverse joints on the dam body on the left bank of Jin'anqiao Hydropower Station,the structure of the transverse joint is modified with a series of simplifications,and then the seismic behavior of the dam monoliths on the left bank is analyzed with the related dynamic analysis method as well.The analysis shows that all the tensile strength and compressive strength at both the toe and the heel and the seismic stabilities of single monolith and monoliths can meet the requirement of the earthquake-resistance specification concerned,which indicates that the dam for Jin'anquao Hydropower Station can withstand the design earthquake with a reasonable design.
