乌鞘岭特长铁路隧道施工通风方案研究

Study on the scheme of construction ventilation in Wushaoling extra-long railway tunnel

乌鞘岭特长铁路隧道在工期要求、辅助坑道数量及其布置形式上有其自身特点 ,同时在施工过程中体现出不同的阶段性特点。依据这些特点 ,并考虑到实际中所遇到的其他因素 ,经过对施工通风方案的研究、比选 ,确定出了最佳的通风系统。整个研究过程 ,揭示出了该隧道施工组织中需考虑及注意的问题 。

Wushaoling extra-long railway tunnel is characterized by the time limit of construction, the amount and arrangement of access drifts and also the specialties in each stage of construction. The best scheme of construction ventilation of the tunnel is determined according to these features and other factors to be encountered in construction after the study and comparison of different options. In the process of investigation, some key problems in the construction organization were revealed and the importance of the coordination between construction organization and construction ventilation was highlighted.
