| 摘 要： | 本文利用目前工程上广泛应用的场地地震反应的一维等效线性化波动方法,计算了不同场地模型在三种不同强度的地震动输入下的地表加速度反应谱。为了研究不同的土层结构对反应谱平台值的影响,本文将计算得到的地表加速度反应谱拟合成建筑抗震设计规范规定的设计反应谱的形式,分析对比了不同的覆盖层厚度、软弱土层对反应谱平台值的影响,得到了一些有价值的研究成果。

| Abstract: | In this paper,ground surface acceleration response spectra(GSARS)of different site models under three ground motion inputs with different intensities are calculated by 1-D equivalent linearization wave method widely used recently in the practical engineering for seismic response of field.The GSARS obtained through calculation are fitted into design response spectra regulated by code for seismic design of buildings to study the effect of different soil layer constructions on platform value of response spectra.The effects of different thickness of overlaying layer& weak soil layer on platform value of response spectra are analyzed,and some valuable research achievements are obtained. |
