摘要
隧道通风方式的选用涉及到隧道长度、交通流量、行车方式、洞口环境保护要求和隧道施工方法等多种因素。介绍了苏锡常太湖隧道的通风系统,重点对纵向通风方式的选取、需风量的计算、排烟设计以及排烟控制逻辑进行了分析。通过实体火灾试验,对排烟设计进行了验证。这些为长大隧道通风排烟系统的设计提供借鉴和参考。
The selection of tunnel ventilation mode involves many factors such as tunnel length,traffic flow,driving mode,environmental protection requirements at tunnel portals and tunnel construction method.The ventilation system of Suzhou-Wuxi-Changzhou Taihu Lake Tunnel is introduced,and mainly focusing on the selection of longitudinal ventilation mode,calculation of air demand,smoke exhaust design and smoke control logic.The smoke exhaust design is verified in a full-scale fire test,which provides reference for the design of ventilation and smoke exhaust system of long and large tunnels.
