城市轨交联通型地下空间火灾风险评估研究

Fire Risk Assessment on the Urban Rail Transit Interconnected Underground Space

通过对城市轨交联通型地下空间火灾风险影响因素分析,构建了包括4个一级指标、14个二级指标、45个三级指标在内的火灾风险评估指标体系;采用模糊综合评估法,从确定因素集、确定评语集、确定指标权重及综合评估等4方面,建立了火灾风险评估模型。运用该评估指标体系和模型,对某地铁上盖综合开发项目进行了评估,并得出评估结果。

By analyzing the influencing factors of fire risk in urban rail transit interconnected underground space, the fire risk assessment index system of this space including 4 first - class indexes, 14 second - class indexes and 45 third - class indexes was constructed. The method of model comprehensive evaluation was adopted to establish an assessing model from four aspects of determining factor sets, determining evaluation sets, calculating index weights and comprehensive evaluation. A combined project over the subway top - cover was evaluated and the evaluation results were obtained through the fire risk assessment model and index system.
