【摘要】 基岩输入参数主要包括基岩面埋深、基岩剪切波速和基岩地震动强度等因素。本文通过分析某场地在选择不同深度的假想基岩面、不同的基岩剪切波速以及不同基岩地震动强度条件下的场地地震反应结果,得出在不同的基岩输入参数条件下,地表的地震动峰值加速度和加速度反应谱存在很大差异。更多还原

【Abstract】 The input parameters of bedrock includes depths of rock interface,rock shear wave velocity,earthquake motion intensity and so on.Through analyzing the result of site earthquake response that gained by selecting different rock interface depths,shear wave velocities and earthquake motion intensities,the conclusion is obtained: with different input parameters of bedrock,the peak values of acceleration and spectra of acceleration on the ground surface have great differences.更多还原
