| 摘 要： | 本文研究确定设计地震动参数中涉及的若干问题,其中包括基岩水平加速度反应谱衰减关系的选择、震源深度对基岩水平加速度峰值及基岩反应谱曲线的影响、强度包络线函数及输入随机相位的选择、土体非线性特性参数和土层剪切波速值的选择、设计地震动反应谱的标定等问题。本文基于一个典型场地计算剖面,采用一维等效线性化模型并通过逐项变换某些研究参数的方法,研究了各种因素对设计地震动参数可能产生的影响及存在的误差和相应的规律。

| Abstract: | This paper relates to some problems about the determination of design ground motion parmeters, which include the choice of the attenuation relationship of rock horizontal acceleration response spectrum, the impact of focal depth to rock peak horizontal acceleration and rock response spectrum curves, the choice of intensity envelops function and random input phase, the choice of soil nonlinearity and shear wave velocity, scale of design ground motion response spectrum ect. In the rearchs of ralative aspect, this paper base on an typical section plane of the engineering site. Through use the method of one dimension model of equivalent linearization, the values of some parameters have been changed to research some possible influence to design ground motion parmeters and the existing errors and corresponding rules. |
