摘要
对同一场地改变土层分层厚度分别建立四种土层反应分析计算模型,输入人工合成的基岩地震波,分别进行土层地震反应分析计算,得到相应的地表加速度峰值和反应谱。对计算得到的结果进行分析比较,最终得出分层厚度对地震动参数的影响。
By changing the layer thickness, four kinds of soil response analysis model established on the same site. And the peak acceleration and response spectrum was got by calculating the seismic response of soil layer with inputs of artificial seismic waves. The effect of layer thickness on ground motion parameters is concluded.
