摘　　要：本文介绍了猴子岩水电站大坝振动台模型试验的概况,包括模型设计、模型制作、加速度传感器埋设、位移测点布置和试验工况设计等,并给出了主要的试验结果。试验研究表明,大坝结构的动力特性受振动强度和振动历史等因素影响,空间位置、输入地震动强度及类型、蓄水等因素对大坝结构的地震反应特性有重要影响。这些研究成果不仅可为大坝的抗震设计提供参考,而且是验证和改进地震动力反应分析方法和计算程序的重要资料。In this paper,the shaking table model tests for Houziyan high concrete faced rock-fill dam are introduced.Design and construction of the model dam,layout of the acceleration sensors and displacement measuring tools,and the work condition design are included.The main test results are presented then,and the results show that the dynamic characteristics of the dam are affected by many factors,such as vibration intensity,vibration history,and so on.The dynamic response characteristics of the dam are affected by the spatial location of the acceleration measuring points,the earthquake type and intensity,the dam impounding or not,and so on.These study achievements can be used to certify and improve the existing dynamic analysis methods or the calculation program,and to be a reference for dam seismic design.
