基于消防性能化设计的高铁站房防排烟系统
Smoke control and extraction system in view of performance-based fire protection design for high speed railway station
摘要：
我国高速铁路客运站房的设计越来越复杂，现行的消防规范具有一定的局限性，已不能满足实际工程设计的需要，引入消防性能化设计手段来解决工程设计中的防火防烟问题就显得尤为重要。结合深圳北站的工程案例，介绍了防排烟设计的难点，对有上盖站台区及高架候车厅的火灾场景分别进行了模拟，并给出了基于消防性能化设计的防排烟措施。
Abstract：
Architectural design of high speed railway station in our country are more and more complex. Due to the limitation, current fire-protection codes cannot satisfy the actual project design, and the performance-based fire protection design is crucially important to solve the smoke control and extraction problem. According to the Shenzhen North Railway Station, presents the difficulty of smoke control and extraction system design, simulates the fire scene for the platform with upper cover and overhead waiting room respectively, and gives the smoke control and extraction measures based on the performance-based fire protection。
