摘要
本文通过对广东省380个项目的地震安全性评价结果进行研究,发现设计特征周期与场地卓越 周期相关,并满足关系式Tg=T(1+kIa),还求出了广东省珠江三角洲地区和潮汕地区的相关常数k和a。
Based on an investigation through the evaluation results of earthquake safety of 380 projects in Guangdong, it is found that the design characteristic period is related to the site dominant period. It also satisfies the relating for mule Tg= T(1+kIa). The relative constants of k and a in Pearl River Delta area and Chousan area in Guangdong province are found.
