由于海上施工竖井布设难度大，致使渤海海峡隧道独头单口掘进长度加大，几个工作面独头单口掘进长度都在25 km左右。本文采用渤海海峡隧道现有的设想方案，通过通风方式的选择、通风计算和通风设备选型对本工程的施工通风进行研究，提出利用巷道式通风解决独头单口掘进25 km隧道施工通风的方案，为渤海海峡隧道的可行性研究提供施工通风方面的技术支持。

The tunneling length of single face of Bohai Strait tunnel increases to 25 km due to the arrangement difficulty of the vertical shafts. The construction ventilation of Bohai Strait tunnel is studied in terms of ventilation mode selection, ventilation calculation and facility selection, on the basis of the existing devised program. In the end, the gallery-type ventilation method is proposed to solve the ventilation problem of the mentioned tunnel. The paper can provide ventilation technical support to the study on Bohai Strait tunnel.
