Risk Analysis and Prevention Measures of Urban Underground Space Fire

城市地下空间发展速度，但其安全问题不容忽视。城市地下空间火灾具有不容易被发现、烟气不容易扩散、人员疏散比较困难、灭火和救援难度大等特点，应采取有效的防范措施。城市地下空间火灾统计分析表明，地下车库和地下商场是地下空间火灾的主要场所，主要原因是电气原因。根据安全检查表和事故树分析，可以确定城市地下空间火灾的风险因素，据此提出了城市地下空间火灾防范对策。
Urban underground space develops rapidly, but its safety problem cannot be ignored. Urban un-derground space fire has the characteristics that fire is not easy to be found and, is not easy to dif-fuse for smoke, is difficult to evacuate personnel and extinguish the fire and rescue, so effective preventive measures should be taken. The statistical analysis of urban underground space fire shows that underground garage and underground shopping mall are the main places of under-ground space fire, and the main reason is electrical. According to the safety check list and fault tree analysis, the risk factors of urban underground space fire can be determined, and the prevention measures of urban underground space fire are put forward.
