摘要： 选取昆明市东川区为研究对象，以结构性危险概率、 功能性危险概率评估地震次生火灾的危险性，引入重大危险源修 正系数后，建立单体建筑震后次生火灾起火概率模型，通过Arc- GIS 平台进行图像、数据分析，评估东川城区建筑地震次生火灾 风险等级。研究表明以框架、砖混结构建筑为主的新城区、中心城 区，建筑密度低、抗震等级高，次生火灾风险低，而以砖砌、土木结 构建筑为主的老城区、边缘行政村，建筑密度大、抗震等级低，次生 火灾风险普遍较高。

Abstract: Taking the Dongchuan district in Kunming as the study object, assess the post earthquake fire risk by structure risk probability and usage risk probability. After introducing the major hazard installation correction factor, the post earthquake fire probability model of single building is built. By image and data analysis on ArcGIS, the post earthquake fire risk level of Dongchuan district is evaluated. The study shows that the buildings in the new district and central district are frame structure and brick concrete structure.They have low density of buildings and high seismic degree, the post earthquake fire risk is low; while the old district and marginal administrative village have high density of buildings and low seismic degree, and the post earthquake fire risk is high.

Key words: post earthquake fire, fire risk assessment, GIS
