地铁同站台高架换乘车站火灾全尺寸实验研究-(1)火灾场景设计

为研究地铁同站台高架换乘车站火灾烟气蔓延特性和防排烟技术，对具有该换乘形式的某实体车站进行全尺寸火灾实验方案设计，结合车站通风排烟模式和列车运行模式，对站厅层、站台层和设备区分别设计不同规模的火灾场景，同时在站内各防烟分区设计安装烟气温度测量装置和流速测试装置，实现同站台高架换乘车站不同结构空间内烟气危险性参数的实时测量。按照本文设计的实验方案在该车站开展了一系列全尺寸实验，后续的研究中将详细介绍不同火源规模、火源位置、通风方式和列车运行模式下的实验结果。

Full-scale experimental study on fire in one-platform-interchange elevated metro station-(1) design of fire scenario

The full-scale fire experiment scheme for a practical one-platform-interchange elevated metro station was designed to investigate the smoke spread characteristics and smoke control technologies of such stations. The fire scenarios with different scale in the station hall, platform and equipment zone were designed respectively combined with the ventilation and smoke exhausting mode and the train operation mode, at the same time, the hazard parameters of smoke in different structure space of the station were measured in real time by designing and installing the smoke temperature measurement devices and flow velocity measurement devices in each smoke bay of the station. A series of full-scale experiments were conducted in this station in accordance with the designed experiment scheme, and the experimental results under different fire source scale, fire source locations, ventilation modes and train operation modes would be introduced in detail in the following studies.
