再谈城市轨道交通电气专业消防设计——结合重庆轨道交通特点谈电气消防设计的重难点

Further Discussion on the Electrical Fire Fighting Design of Urban Rail Transit——Discussion on Key and Difficult Points of Electrical Fire Fighting Disign Based on Characteristics of Chongqing Rail Transit

建筑电气消防设计一直以来都是设计审查的重点,城市轨道交通作为大型公共建筑,电气消防更不容忽视。因城市轨道交通主要为地下公共建筑,在设计时与其他地面上的公共建筑执行相同规范时,很多条款实施起来有一定的难度,2018年5月国家发布了GB 51298-2018《地铁设计防火标准》,在很大程度上解决了这一问题。又因重庆山城的独特地势原因,线路起伏较大,深埋车站较多,在同其他各大城市的轨道交通执行相同的防火标准时,又会存在因地域特点造成的一些问题。针对以上情况,结合重庆轨道交通新一轮建设,再谈重庆轨道交通车站电气消防设计的重/难点,并提出问题,以备今后的深入研究和探索。

The design of electrical fire protection of buildings has always been the focus of the design review.Electrical fire protection should not be ignored for urban rail transit as a large-scale public building.Since urban rail transit is mainly an underground public building,many terms and clauses are difficult to implement when the same regulations are implemented for other public buildings on the ground during design.GB 51298-2018 Standard for Fire Protection Design of Metro issued by the state in May 2018 solves this problem to a large extent.In addition,due to the unique topography of Chongqing as a mountain city,large line undulation and many deep-buried stations,there are some problems caused by the regional characteristics when the same fire prevention standards of rail transit in other major cities are implemented.In view of the above condition,combined with the new round construction of rail transit in Chongqing,this paper discusses the key/difficult points of the electrical fire protection design of rail transit stations in Chongqing,and puts forward some problems for further study and exploration.
