中文摘要：

为了为水坝发现动态扩大系数的分发模式，使遭到了到地震， 3D 有不同高度和河山谷的不同形状的面对水泥的 rockfill 水坝的地震回答被使用等价物线性的模型分析。统计分析也被做到地震系数，并且为计算最大的加速的一个实验公式被提供。结果在一样的水坝高度和一样的基础加速刺激的条件下面显示那，随河山谷宽度的增加，水坝的顶的轴上的最大的加速的位置相称性地从中心搬到河边。为狭窄的山谷，最大的加速在水坝的顶发生在轴的中间；为宽山谷，最大的加速出现在河边附近。结果否定 2D 的申请为宽山谷的动态计算，和为高面对水泥的 rockfill 水坝的地震反应，沿着轴的地震系数应该被给的表演，除了那沿着水坝高度。用伪静电干扰方法的 rockfill 水坝的地震稳定性分析能根据公式被修改。

英文摘要：

To find the distribution patterns of dynamic amplification coefficients for dams subjected to earthquake, 3D seismic responses of concrete-faced rockfill dams with different heights and different shapes of river valley were analyzed by using the equivalent-linear model. Statistical analysis was also made to the seismic coefficient, and an empirical formula for calculating the maximum acceleration was provided. The results indicate that under the condition of the same dam height and the same base acceleration excitations, with the increase of the river valley width, the position of the maximum acceleration on the axis of the top of the dam moves from the center to the riversides symmetrically. For the narrow valleys, the maximum acceleration occurs in the middle of the axis at the top of the dam; for wide valleys the maximum acceleration appears near the riversides. The result negates the application of 2D dynamical computation for wide valleys, and shows that for the seismic response of high concrete-faced rockfill dams, the seismic coefficient along the axis should be given, except for that along the dam height. Seismic stability analysis of rockfill dams using pseudo-static method can be modified according to the formula.
