填充混凝土处治隧道围岩突变实践技术

Practical Technology of Filling Concrete to Treat Sudden Changes in Tunnel Surrounding Rock

隧道的围岩变形处治是隧道施工技术管理的重点、难点,也是隧道能否安全顺利贯通的关键,随着我国隧道施工技术的不断进步,各类隧道施工世界级的技术难题被攻克,通过云南某高速采用填充混凝土进行围岩突变紧急处置的实践应用,对施工技术进行了系统性总结。

The treatment of surrounding rock deformation in tunnels is a key and difficult point in tunnel construction technology management,and it is also the key to whether tunnels can be safely and smoothly connected.With the continuous progress of tunnel construction technology in China,various world-class technical problems in tunnel construction have been overcome.Through the practical application of filling concrete for emergency treatment of surrounding rock mutation on a highway in Yunnan,a systematic summary of construction technology has been carried out.
