| 摘 要： | 在研究多个工程场地钻孔资料的基础上,选取和构造了若干典型场地剖面,利用目前工程上广泛应用的场地地震反应分析的一维等效线性化波动方法,计算了各剖面在不同基底地震动输入的反应谱值及地表加速度峰值,分析了覆盖层厚度对反应谱峰值及峰值周期、地表加速度峰值和放大倍数的影响,得出了一些有意义的结论。

| Abstract: | Based on the research of many bore data of engineering sites, some representative site profiles are selected and built. The response spectrums and ground peak accelerations of the profiles under different input seismic motions are calculated by 1-D equivalent linearization wave motion method for site seismic response analysis. The effects of the thickness of overlaying layer on response spectrum peak, period corresponding to response spectrum peak, ground peak acceleration and magnifying multiple, as well as some significant conclusions are elicited. |
