乌鞘岭特长隧道方案设计

Tentative project of Wushaoling tunnel

乌鞘岭隧道为目前我国最长的铁路隧道 ,长 2 0 .0 5km ,其地质条件复杂、工期极其紧张、工程规模巨大 ,引起了国内外地下工程界的瞩目。文章通过越岭隧道限坡、长度、单双洞方案比选介绍了乌鞘岭特长隧道方案选择情况 ;并从隧道施工方案、防排水、运营和施工通风等方面较为系统地介绍了隧道的设计概况。

Wushaoling tunnel, the longest tunnel in China at present with a length of 20050m , attracts the attention in the field of underground works due to its complex geological condition, strict time limit of construction and tremendous engineering work. This paper introduces the selection of the tentative projects of this watershed tunnel in the respect of limit slope, tunnel length and the comparison between a double-track tunnel or twin single track tunnels and gives a general introduction to the design of this extra-long tunnel in regard to construction plan,waterproofing and drainage, operation and construction ventilation.
