清平面板堆石坝抗震分析

ANALYSIS OF SEISMIC RESPONSE FOR QING PING CONCRETE-FACED ROCKFILL DAM

摘要: 根据面板堆石坝的结构特点和工作条件,采用动力非线性有限元法,对清平水库面板坝进行了空库和满库条件下地震反应分析与比较、混凝土面板地震抗滑稳定分析及坝基饱和细砂层的地震液化验算,综合评价大坝的安全性。

Abstract: Based on the structural characterishcs and service conditions of Concrete-Faced Rockfill Dam (CFRD), the seismic response of Qing Ping CFRD is studied using non-linear dynamic FEM. Comparison is made between the results Under two different conditions: reservoirempty and reservoir-full. The anti-slide stability of the concrete face and the liquefaction of the sand in the dam foundation are discussed. Finally, the safety of the dam is appraised.
