中文摘要：

坝体在地震作用下的加速度反应、残余变形和破坏是土石坝动力分析的重要内容。针对狭窄河谷中猴子岩高面板堆石坝的特殊结构形式,设计、制作了高达1m的大坝坝段模型和整体模型,进行大型地震模拟振动台模型试验。研究了大坝加速度反应的空间分布规律及相关因素对坝体加速度反应特性的影响,分析了大坝地震残余变形和破坏的发展过程和破坏机理。研究表明：面板对堆石坝体的加速度反应有明显的限制作用,不对称河谷中高面板堆石坝两岸侧坝体的加速度反应水平差异明显;高面板堆石坝的地震残余变形量值相对较小,坝体抗震性能良好,但猴子岩水电站开关站所在下游压重体平台是整个大坝结构抗震的薄弱环节,应当在设计中重点予以考虑。

英文摘要：

Acceleration response,seismic residual deformation and dynamic failure of dam in earthquake are the important contents of dam dynamic analysis.Two Houziyan high concrete face rock-fill dam models（2-D and 3-D）which are 1.0meter high were designed and constructed considering the valley topographic of dam site and dam＇s structure features.Firstly,the acceleration response characteristics of dam was studied deeply;then,the seismic residual deformation process and the dynamic failure mechanism of dam were analyzed comprehensively.The study shows that,the acceleration response amplitude of dam was reduced because of the impacts of concrete face slab,and the amplification effects of dam to bedrock inputting earthquake on left and right river bank was different obviously;seismic residual deformation of the concrete face rock-fill dam is relatively lower,and the anti-seismic performance of dam is well;the downstream kentledge platform of dam that switch station of the water power station was constructed on it is the weakness of dam system in earthquake,and the specific anti-seismic design for it is necessary.
