武汉轨道交通7号线越江区间通风系统研究
Research on ventilation of cross-river section of Wuhan Rail Transit Line 7
摘要：
介绍了武汉轨道交通7号线越江区间的公铁合建隧道的运营通风设计，并针对火灾工况，比较了4种排烟方案的排烟模式、风道漏风、风机配置的优缺点，确定了五段排烟方案，并对典型火灾工况进行了模拟计算，可满足火灾排烟要求。

Abstract：
Presents the operational ventilation design for cross-river section of Wuhan Rail Transit Line 7 which is a highway and railway highway-metro cross-river tunnel. According to the fire condition, studies the advantages and disadvantages of smoke exhaust mode, air leakage from air duct, and fan configuration of four schemes. Confirms five section smoke extraction scheme. Simulates the typical fire conditions. The scheme can meet the requirements of fire and smoke extraction.
