| 摘 要： | 本文采用有限元法进行了九甸峡带垫座拱坝的静动力分析 ,着重讨论了垫座对坝体反应的影响 ,垫座合理尺寸的确定。分析结果表明 :垫座的设置对坝体的静动位移影响较小 ,坝体的静动应力虽在分布上稍有不同 ,但也无实质性变化。对九甸峡这类地质条件有缺陷的拱坝坝基 ,可以采用加垫座的工程措施进行处理。

| Abstract: | Static and dynamic analyses for the Jiu Dian Xia Arch Dam with pedestal are conducted by finite element method.Especially,the pedestal's influence on dam body responses and its reasonable size are discussed.The results indicate that the pedestal setting has a small influence on the static and dynamic responses of the dam body,including displacement,and stress distributions.Setting a pedestal is an effective engineering meaure for an arch dam base of disadvantageors geology condition,Such as Jiu Dian Xia Arch Dam. |
