大型综合交通枢纽城际地下车站公共区防排烟系统设计

摘要

在综合考虑新郑机场城际地下站的站址环境、建筑布局、外部接口、机房布置、风亭位置等特点的基础上，采取将车站公共区及列车轨行区域划分独立分区，分别设置独立防排烟系统的设计方案，避免了建筑形式复杂、排烟距离过长带来的不利影响，解决了此类复杂超规地下建筑的防排烟问题。%This design was based on a comprehensive consideration about the relevant characteristics of an intercity-railway underground station at the Xinzheng Airport, including the station site environment, architectural layout, external interface, machine room layout, ventilation pavilion location and so on. In the design, this scheme was adopted: dividing the station public area and the tracked area into independent subareas with independent smoke control systems. As a result, the adverse effects caused by complex architectural form and by overlong smoke-extraction distance were avoided, and the problem in smoke control for complex and super-gauge underground building like this was solved.
