Algorithm for estimating probability of seismic fire in city
城市居民区地震火灾发生率的推估方法
Abstract : this paper suggests a general model for hazard analysis of urban post - earthquake fire . based on the statistic study of urban fire , a modified calculating formula for occurrence of urban post - earthquake fire is established . according to poisson process model , a general analysis method is suggested . the analysis result is depicted by exceedance probability curves . the example analysis for a practical project is given in the paper
文摘:建议了一个城市地震次生火灾危险性分析的一般模型.利用民事火灾的统计分析结果,给出了城市地震次生火灾发生率的修正公式.在此基础上建议了地震次生火灾危险性分析方法,并以超越概率曲线的方法表达次生火灾危险性分析的结果.结合实际工程,给出了分析实例
