铁路隧道浅埋下穿高速公路施工技术

Discussion on Construction Technology of Shallow Tunnel in Railway Tunnel

随着我国铁路交通事业的不断发展,其要应对的施工条件越来越复杂多变,其中铁路与公路立体交叉相互穿越的情况大量增加。探讨并恰当运用铁路隧道以浅埋下穿形式穿越高速公路之建造工艺变成了铁路工程建设不可回避的施工难题。该隧道建造工艺包括暗挖段建造工艺和明挖段建造工艺,笔者立足于工程实践,对此两项工程技术展开深入探讨。通过实践证明,此两项铁路隧道施工工艺能够有效加快工程施工进度,达到理想工程效果。

with the constant development of the railway transportation industry in our country, its construction conditions to deal with more and more complicated, the railway and highway interchanges across a large increase in the condition of each other.Explore and appropriate use of railway tunnel with shallow buried wearing form across the highway construction process into the railway engineering construction of unavoidable construction problems.The tunnel construction process including underground running Duan Jianzao process and Ming dig Duan Jianzao process, the author based on the engineering practice, the two engineering technology are studied.Through the practice has proved that the two railway tunnel construction technology can effectively speed up the construction progress, achieve ideal engineering effect.
