浅埋软弱地层(滑坡体)隧道进洞施工技术研究

摘要

张花高速公路刘家院子隧道右洞洞口处于浅埋坡积体中,直接开挖进洞容易导致山体滑坡,造成隧道衬砌开裂.介绍了用抗滑桩处理滑坡体的技术,处治之后山体稳定,保证了隧道衬砌结构的安全,对山岭隧道施工有一定的借鉴意义.%Liu jia yuan zi tunnel is shallow integrated break in zhang hua highway,conventional excavation may bring out mountain landslide easily,and cause tuunel lining to crack.This article describes the technology of dealing with landslide by anti-slide pile,and has some referential significance for the tunnel construction.
