华东地区评估和推算场地最大水平加速度的一种实用方法

APPRATICAL METHOD USED FOR THE EVALUATION AND CALCULATION OF MAXIMUM HORIZONTAL ACCELERATION IN THE REGION OF FAST CHINA

本文提出华东地区以地震地质确定性方法为场地工程勘察估算最大水平加速度的具体步骤,并指出如何考虑远、近场地震对场地地震动的影响,使提出的场地地震动参数更加合理,从而达到提高重大工程的安全度。

This paper presents a procedure for evaluating the maximum horizontal accel- eration on site investigation by the seismogeological method in the region of east China, and shows how to consider the effects of far-field earthquake and near- source earthquake in ground motion. It is possible that this method of determining the parameter for ground motion is more reasonable and that a high safety factor could be obtained for a great project.
