海底隧道进口段通风设计

Ventilation Design of the Entrance Section of the Submarine Tunnel

通风一直是长大隧道的一个难题,尤其青岛胶州湾海底隧道断面大,通风距离长。根据青岛胶州湾海底隧道有服务隧道的特点,进行服务隧道和主洞的联合通风设计,并根据施工阶段的不同,采用不同的施工方案。

Ventilation is a difficult problem in long tunnels. Especially in the submarine tunnel in Jiaozhou Bay, Qingdao, which has big section and long ventilation distance. With regard to the characteristic of the submarine tunnel in Jiaozhou Bay, Qingdao as a serving tunnel, this paper proposes a ventilation design of the combination of serving tunnel and the main tunnel. Different construction schemes are adopted according to different construction stages.
