摘要
本文从双态泊松模型的基本概念出发,给出了它应用于地震危险性分析中的简化公式。通过数值算例说明了地震活动状态参数(包括两态下的平均发生率、相互转移概率和初始状态参数)对地震危险性分析结果的影响。文中并讨论了该模型与简单泊松模型和一般非齐次泊松模型的关系以及它在地震危险性分析应用中的若干问题。
A simplified formula of using the two-state Poisson model to analyse the seismic hazard is given in this paper.The influence that the seismicity parameters have on the results of seismic hazard analysis is demonstrated through numerical examples.These parameters include the mean occurrence rate under the two states,the transition probabilities between the two states and some initial values.In addition,some problems encountered in the application of this model to seismic hazard analysis are discussed as well as its relations to simple Poisson model and general nonhomogeneous Poisson model.
