摘要:
为了解在不同通风模式下地铁十字换乘车站站台火灾发展规律，通过在地铁十字换乘车站站台开展全尺寸火灾实验，分析了不同通风模式下站台层火灾的烟气扩散速率、沉降高度和扩散范围。研究结果表明：该类型车站站台火灾烟气扩散受到建筑结构和通风条件等因素的影响；在A线路站台层发生火灾时，站台断面面积沿烟气扩散方向的缩小有效抑制了烟气向远端扩散；站台机械通风能够有效降低烟气扩散速率，控制烟气扩散区域和沉降高度；在0.5 MW火灾规模下，A线路站台火灾对B线路影响不明显。
Abstract:
In order to fully understand the fire development laws of platform in the cross transfer metro station under different ventilation modes, the fullscale fire experiments were carried out on the platform of cross transfer metro station, and the parameters of platform fire, such as smoke diffusion rate, smoke settlement height and smoke diffusion range under different ventilation modes were analyzed. The results showed that the smoke diffusion of platform fire for this type of station was affected by the building structure and ventilation conditions. When the fire occurred on the platform floor of Line A, the reduction of platform crosssection area along the direction of smoke diffusion effectively restrained the smoke diffusion to the far end. The mechanical ventilation of platform could effectively reduce the smoke diffusion rate, control the smoke diffusion area and settlement height. For the 0.5 MW fire, the platform fire of Line A had little effect on Line B.
