分析城市地下交通枢纽常见的消防设计难点,提出将换乘空间设计为准安全区、商铺之间采用防火玻璃加喷淋的分隔方式、借用相邻防火分区疏散、采用下沉式广场或避难走道等消防策略。结合具体工程,从防排烟设计、防火分隔、消防系统设计、疏散系统设计等方面提出加强措施。利用FDS和Pathfinder软件对客流集散区进行火灾烟气和人员安全疏散模拟分析,验证消防设计的可行性。
Analysis of the common urban firefighting design of underground transport hub, proposed the design of the transfer space for the quasi-safe area, between shops using fire glass and spray separation, borrow adjacent fire partition evacuation, the use of sunken plaza or refuge walkway Such as fire strategy. Combined with specific projects, from the smoke exhaust design, fire separation, fire protection system design, evacuation system design and other aspects of strengthening measures. The use of FDS and Pathfinder software for passenger flow fire evacuation and fire evacuation simulation analysis to verify the feasibility of fire design.
