摘　　要：本文采用建筑物震后火灾发生与蔓延危险性分析的概率模型[1],给出建筑结构在地震破坏状态下的次生火灾发生的概率。通过综合分析其它影响因素,给出判定城市地震次生火灾发生的高危险区的方法。并在GIS(GeographicInformationSystem)下实现对城市地震次生火灾高危险区的划分。In this paper the authors used probability model for hazard analysis of post-earthquake fire occurrence of buildings ^(\) and calculated the probability of the secondary fire disaster occurrence of buildings following an earthquake. Through synthetical analyzing of other influence factors, the method for determining high hazard area of the secondary fire is provided and the system for the high hazard area determination of secondary fire occurrence in cities based on GIS(Geographic Information System)is completed.
