地下建筑火灾风险分析

Fire risk analysis of underground building

从系统角度出发,构建以建筑结构、火源及火灾荷载情况、消防设施、地下疏散能力以及消防安全管理水平为准则层的地下建筑火灾安全风险指标体系,利用改进的层次分析法确定地下建筑火灾风险因素权重,且结合综合评价模型计算地下建筑火灾安全风险等级。实例应用研究表明,该方法能够用来分析评价地下建筑火灾风险安全等级,可为消防监督分级管理提供参考。

From the viewpoint of system,underground building fire safety risk index system was constructed,and the building struc-ture,fire source and fire load,fire facilities,underground evacua-tion capacity and fire safety management level were the criterion layer.Using the improved analytic hierarchy process to determine the weight of underground building fire risk factors,and combined with the comprehensive evaluation model to calculate the risk level of underground building fire safety.The application showed that the evaluation method can be used to analyze and evaluate the fire risk safety level of underground buildings,and can provide a useful reference for fire supervision classification management.
