隧道穿越富水破碎砂质泥岩浅埋段施工技术

The Construction Technology of Tunnel Passing Through Shallow Buried Section of Water-Rich Broken Sand Mudstone

以兰海高速渭武大草滩隧道为例,研究分析了隧道在穿越富水破碎砂质泥岩浅埋段时在隧道洞内,洞外采取的一系列技术措施,为隧道顺利穿越富水破碎砂质泥岩浅埋段施工提供参考。

Taking Weiwu Dacaotan tunnel of Lanhai highway as an example, this paper studies and analyzes a series of technical measures taken in and outside the tunnel when the tunnel passes through the shallow buried section of water-rich broken sandy mudstone, to provide reference for the tunnel smoothly passing through the shallow buried section of water-rich broken sandy mudstone.
