利用大型三向六自由度地震模拟振动台，对我国三峡工程溢流坝段进行了动力模型试验。试验真实模拟了复杂的大坝结构及坝体与库水的动力相互作用。在全面分析了大坝的动力特性及其在多类地震输入下的地震反应后，对大坝的抗震安全性作出评估，得出了一些可作为设计依据的有益结论。
Using large scale three-directional and six-degree-of-freedom seismic simulation shaking table, dynamic model test is carried out for the overflow dam section of the Three Gorges Project in China. The experiment simulates the complicated dam structure and the dynamic interaction between dam and reservoir water. After comprehensively analyzing the dynamic characteristics of the dam and its seismic responses under various types of earthquakes, the seismic safety of the dam is evaluated and some beneficial conclusions are obtained.
