| 摘 要： | 本文以核动力工程和大型水电等工程场地地震危险性分析结果为样本,统计分析了我国不同超越概率水平的基岩水平向地震动峰值加速度(PGA)之间的关系。结果表明:①PGA随超越概率水平增大,其降低幅度存在稳定的比例关系;②上述关系在不同地区和不同基本烈度地区没有显著差异。

| Abstract: | Based on the results obtained from seismic safety evaluations of critical engineering projects such as nuclear power plants and large hydroelectric energy engineering,we propose a statistical relationship of the ground motion peak acceleration with different probability levels in China.Our result shows that:(1)the PGA decreases proportionally with the increase of exceeding probabilities;(2)for the purpose of engineering application,the variation of PGA in different intensity regions may be ignored. |
