摘　　要：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。Dynamic model test of overflow dam section of Three Gorges Project was carried out on a large-scale vibration actuating system. The test simulated the real complex dam structure, and action of dam body and reservoir water on each other. Dynamic properties of the dam were entirely analyzed. Responses to many kids of emulated earthquake motions were also analyzed. Dam safety against earthquakes was evaluated. Some useful conclusions that can be used as basis of design have be obtained.
