| Along with the progress of the society and the development of the city, the subway ispublic transportation modernization of its increasingly important role. But at the same time, thesubway station complex internal architecture, many kinds of electrical and mechanicalequipment, a large amount of electric equipment, air conditioning unit, wire and cable andoffice and living facilities are likely to be potential factors of fire, while electric bus operation inmany parts may be due to overload, overheating insulation damage caused a fire, and the fire,high temperature will produce a lot of smoke and toxic gases, resulting in some material stationrenovation and electric passenger car body, increasing the risk of subway fire. Risk factors forso many may cause the subway fire, the need to take effective measures to assess andprevention. Subway fire safety assessment method of existing, mostly from a subjective pointof view, on the basis of qualitative evaluation experience artificially, the lack of scientificquantitative evaluation method. Therefore research on subway fire safety assessment model ofsubway fire safety, security, strengthening the fire hazard investigation dynamics, cogentaccomplish subway safety prevention is important.Subway fire safety is related to the safety of subway engineering, and relates to manyaspects of emergency command, engineering design, not only need the system engineeringtheory, also need a method of quantitative calculation. This paper is based on the prior to theaccident, Based on a theory of modern safety management, combined with the excellent casesof domestic and foreign security system construction, to explore the status of fire safety in ourcountry and factors of influence of subway fire safety. Through the years around the metro fireaccident data collection, collation, deeply influencing factors, using the method of clusteranalysis and the fish bone diagram comprehensive analysis on the factors affecting the subwayfire safety work, and according to the theory of fault tree, stratified on direct cause of subwayfire safety and potential factors, establishes a set of complete subway fire safety evaluationsystem. Using the theory of F-AHP, analysis model by using the evaluation index system of thelevel, design questionnaire, based on the construction of subway fire safety evaluation model ofthe comprehensive evaluation method, and taking Shenzhen Metro as an example to evaluatethe empirical analysis. Based on the results of analysis, from the equipment, management,personnel, information, goods, environment six aspects put forward countermeasures andmeasures to strengthen the subway fire safety work. |
