超长换乘通道建筑消防研究

Study on Fire Prevention for Extra Long-distance Transfer Channel Building

现行的国家工程建设消防技术标准均未明确城市轨道交通换乘车站间超长换乘通道如何进行建筑消防设计,比如换乘通道内安全出口的设置、疏散总人数的确定、疏散宽度的计算及疏散时间的验算等。该研究以相关规范条例作支撑,对观音桥站超长换乘通道进行消防设计,并与相关消防部门多次对接沟通达成共识,确保超长换乘通道建筑消防的安全性、科学性及合理性。该文对满足超长换乘通道的建筑消防设计有一定的指导作用。

None of the current fire prevention technical standards for national project construction has offered building fire prevention/fighting design for the extra long-distance transfer channel between urban rail transit interchange stations, including the setting of the exits in the transfer channel, the determination of the evacuation population, the calculation of the evacuation width, and the checking of the evacuation time. Supported by the relevant codes and regulations, this study designs a fire prevention design for the extra long-distance transfer channel at Guanyinqiao Station, and ensures its safety, rationality and scientific basis by reaching consensus with the relevant fire department. This paper can moderately guide the fire protection design for extra long-distance transfer channel buildings.
