| 摘 要： | 本文在研究我国数百个工程场地钻孔资料的基础上，选取和构造了若干有代表性的典型场地剖面，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，计算了不同场地在三种不同强度的地震动输入下的地表加速度峰值反应。分析研究了覆盖层厚度、软土层的埋深与厚度等对场地地表加速度峰值的影响，得到了一些有意义的结论。

| Abstract: | In this paper, based on hundreds of actual engineering site profiles, the authors select and build several significant site profiles, which include the thickness of overlaying layer, the depth and thickness of soft soil layer at site. The ground peak accelerations of different soil layer constructions are calculated under three different intensity earthquake inputs through the equivalent linearization and wave propagation method for the earthquake response analysis of soil layers. The effect of the thickness of overlaying layer, the depth and thickness of the soft soil layer at site is analyzed, and some conclusions with realistic significance are arawn. |
