摘要
本文基于我国已有的二十余个重大水利水电工程场地地震危险性分析的结果,运用概率分析方法探讨了水电工程抗震设防的概率水准和地震作用的概率模型,以便为正在修订中的《水工建筑物抗震设计规范》提供依据。
In this paper,based on the statistic analyses of the data of site-specific seismic hazardevaluations of more than twenty important hydraulic projects designed of under construc-tion in China,a proposed probabilistic level of fortification against earthquake and theprobabilistic models of seismic actions are discussed.The results are recommended for thedynamic reliability analyses of important hydraulic structures such as dams to suit the re-quirments of the new《Earthquake Resistant Design Code of Hydraulic Structures of Chi-na》,which is now being revised.
