| 摘 要： | 采用和混凝土力学性能相似的仿真混凝土材料,结合振动台试验技术,对模型进行合理设计。采用逐级加载方法,研究阿海碾压混凝土重力坝厂房坝段在地震荷载作用下的动力破坏发展过程及地震破坏形态。试验结果表明:引水管和坝体相交的坝头部位是厂房坝段的抗震薄弱部位;大坝开裂后坝体的整体刚度迅速下降,可以结合坝体基频、残余应变的变化以及对坝体表面宏观裂缝的观察,综合分析大坝的损伤破坏过程。试验结果为工程设计人员进行大坝抗震设计提供了参考。

| Abstract: | Taking simulated concrete and in the combination of experimental technology of shaking table,the model of Ahai power house dam monolith is reasonably designed.By step-loading,the seismic failure process and mode of the dam monolith are studied under seismic load action.The results show that the intersectant point of the dam body and the intake pipe is the weak point for anti-seismic;the general stiffness decreases rapidly after dam cracking.The damage and failure process of the dam monolith can be comprehen... |
