摘　　要：本文以苏州市某高大空间地铁车站为实例,分析了将站厅站台公共区楼扶梯洞口打通形成高大空间引发的楼扶梯口风速、火灾模式控制等有别于常规车站的重难点问题,并提出了在站台公共区两侧设置封闭楼梯间专门用于乘客安全疏散,同时解决了楼扶梯楼风速问题,提高高大空间的排烟量计算标准和与车站隧道通风系统结合的火灾控制模式的解决方案,同时采用火灾分析模拟软件(简称“FDS”)对多种火灾工况模拟验证了方案的合理性,满足各项规范要求。Taking an atrium subway station in Suzhou as an example, this paper analyzes the major and difficult problems caused by the opening of the escalator openings in the public area of the station hall and platform to form a tall space, which are different from those of conventional stations, such as the wind speed and fire pattern control at the escalator entrance. The closed stairwells are set up on both sides of the public area of the platform for the safe evacuation of passengers. At the same time, it solves the problem of wind speed on the stairs and escalators, improves the calculation standard of smoke exhaust in tall spaces, and is a solution for the fire control mode combined with the station tunnel ventilation system. At the same time, the fire analysis and simulation software( "FDS" for short) was used to simulate the rationality of the scheme for various fire conditions and meet the requirements of various specifications.
