心墙堆石坝和面板堆石坝是目前高地震烈度区高坝建设中普遍采用的两种高土石坝坝型，它们的动力反应特性和抗震性能是水电工程界普遍关注的问题。本文基于双江口高心墙堆石坝、两河口高心墙堆石坝和猴子岩高面板堆石坝等3个实际工程的大坝大型地震模拟振动台模型试验，对比、分析试验结果，研究高土石坝地震动力反应特性，重点考察了两种坝型（心墙坝和面板坝）地震动力反应特性的异同点。研究表明：高面板堆石坝和高心墙堆石坝均有良好的抗震性能；水库蓄水对两种坝型结构动力特性参数变化的影响规律有所差异；面板对堆石坝上游坝坡的保护作用明显，有效抑制了上坝坡的加速度反应；面板堆石坝虽然抗震性能优良，但对面板相关的设计和施工水平依赖性很强。

The dynamic response characteristics and the anti-seismic performance of core rock-fill dams and concrete faced rock-fill dams constructed in the region of high earthquake intensity are the marked fo?cus in the field of hydropower engineering. In this paper,large-scale shaking table model tests for three re?al high rock-fill dams,the Shuangjiangkou core rock-fill dam,the Lianghekou rock-fill dam and the Houz?iyan concrete faced rock-fill dam, were performed firstly, and then, the dynamic response characteristics of high rock-fill dams in earthquake were studied deeply on the basis of contrast analysis to the test re?sults. The same and different points for dynamic response characteristics of core rock-fill dam and concrete faced rock-fill dam are the key concerns in the study. The results show that both high core rock-fill dam and high concrete faced rock-fill dam have good anti-seismic performance;the influence law of reservoir impoundment on the changes of dam structure dynamic characteristic parameters for the two dam types are different;the protective effect of concrete face on the dam slope stability is obvious, suppressing the accel?eration response of dam slope up-stream effectively;although the anti-seismic performance of concrete faced rock-fill dam is wonderful, the dynamic stability of dam in earthquake depends greatly on the design capabilities and the construction quality of concrete face.
