摘要:
为研究地铁网络化运营枢纽车站火灾烟气扩散特征和防排烟技术,根据工程资料和标准规范对典型多线换乘车站进行1∶10火灾实验模型设计,并依据设计方案完成车站模型主体结构和通风排烟系统的搭建,同时在各个防烟分区设计安装温度、流速、烟气浓度和热辐射测量装置,可实现对“T”形、“十”形和“L”形换乘等不同换乘形式车站的火灾场景模拟和危险参数测量。研究结果表明:该模型装置能够开展一系列针对不同换乘形式和通风模式的火灾实验,对于全面揭示大型换乘车站火灾烟气运动规律、验证并优化火灾防排烟设计方法、支撑复杂结构枢纽车站火灾烟气控制技术具有重要意义。
Abstract:
To investigate the fire smoke spread characteristics and the smoke control and exhaust technologies in the hub station of metro network,a 1:10 fire experimental model of typical multiline transfer station was designed according to the engineering documents and standard specifications.The main structure of station model and the ventilation and smoke exhausting system were established according to the design scheme,meanwhile,the measurement devices of temperature,flow velocity,smoke concentration and thermal radiation were designed and installed in each smoke control zone.The model device could realize the fire scenarios simulation and dangerous parameters measurement of station with different transfer types such as T shape,cross shape and L shape.The results showed that the model device could be used to carry out a series of fire experiments focused on different transfer types and ventilation modes,which is of great significance for fully revealing the smoke movement law in the fire of large transfer station,verifying and optimizing the fire design method of smoke control and exhaust,and supporting the fire smoke control technologies in the hub station with complex structure.
