城市公共安全——地下场所火灾危险性

City Public Safety-Fire Risk of Underground spaces

采用层次分析方法分析了地下场所的火灾危险性。按地下场所功能不同分为地下商城、停车场、地铁站和娱乐场所,以火灾载荷、火源、人流量、财产损失及疏散和救援为评价因子,建立了地下场所火灾危险性的递阶层次结构模型,建立各层次的判断矩阵,通过计算得到不同功能地下场所的总权重值并进行排序,得到地下场所火灾危险性严重程度为商场>娱乐场所>地铁站>停车场的结论。

AHP（ Analytic Hierarchy Process） was used to Analyze the fire risk of underground spaces. According to different functions,underground spaces was divided in four places as underground mall,parking area,subway stations and entertainment place. By evaluation factors of the fire load,the fire source,the flow of people,property damage and evacuation and rescue,the fire risk of hierarchical structural model was established with various levels of judgment matrix for underground spaces. Then,the total weights of underground places of different functions can be obtained and sorted by calculating. The results show that the severity of fire risk in underground spaces was that underground mall entertainment subway station parking area.
