| 摘 要： | 复合地基在我国土木工程领域应用广泛。这类场地的地震反应如何呢？这对于结构设计的地震动输入是一个重要的问题。本文使用二维有限元分析程序--FLUSH，计算不同输入波和不同置换率情况下的地表加速度峰值和加速度反应谱，并围绕置换率对场地地震反应的影响进行了分析讨论。

| Abstract: | In China, composite foundation has been widely used in civil engineering. What is the seismic response of this type of site? This is an important issue as to the input earthquake motion for structure design. By using the two-dimensional finite element program–FLUSH, the ground surface peak acceleration and acceleration response spectra of different replacement ratios under different ground motion inputs are calculated. The influences of replacement ratio on seismic response are studied; and some valuable results are obtained. |
