| 摘 要： | 以景洪水电站重力坝大孔口坝段为研究对象，通过输入没特性地震波的振动台模型试验和三维有限元分析，定量、定性地研究了大孔口坝段地震反应的特性。结果表明，对于大孔口坝段使用现行抗震规范反应谱曲线乍得的结果偏小；用振型迭加计算大孔坝段地震响应，参与迭加的振型不应少于五阶；应充分考虑不同地震特性的影响。

| Abstract: | In this paper,the dynamic characteristics and responese of a large holed dam section of gravity dam are tested and studied by inputting the various earthquake waves with the different time domain and frequency domain features into a shaking table.The results show that(1)the computational values based on the existing aseismic code are obviously smaller than those of time history analysis and dynamic model test,(2)the first 5 modal shapes or more than should be considered in the aseismic analysis if the modal superposition technique is used for including the influence of the higher modes on vibration;(3)the account from the various features of earthquake waves must be taken into in analysis. |
