The seismic zoning map was worked out separately by use of earthquake intensity and peak value of horizontal acceleration of bedrock.

区划图是分别用地震烈度和基岩水平加速度峰值来编制区划的。

The peak acceleration responses are fully controlled by the relative stiffness ratio and the input seismic excitation, and their distributions are quite complicated.

随着节点相对刚度比的增加，结构在地震作用下的峰值加速度反应受输入地震波能量分布特征的控制，分布规律非常复杂。

Then some rules are presented: the frequency characteristics, acceleration peak value of the input ground motion have great influence on the seismic response of composite foundation.

结果表明：输入地震动的强度和频谱特性对复合地基地震效应影响较大；
