摘要
系统阐述了地震危险性分析方法发展中三种典型概率模型的特点和实质，它们被分别称之谓：简单概率模型、分段泊松模型以及复合概率模型。在此基础上，提出了一种基于复合概率模型的地震影响场等效地震的计算方法。
Three typical models which are called in this paper as “simple probability”,“segment Poisson” and “ complex probability” are described in detail during development of seismic hazard analysis. Based on the complex probabilistical model,a method of calculating the magnitude and distance of equivalent earthquake in seismic effect field is suggested and an example of the application is presented to the seismic safety evaluation of engineering site.
