摘要
以中南通道铁路(瓦日线)吾沿河隧道病害治理为工程背景,针对地下水、基底虚渣、软弱围岩、地应力等因素造成的隧道基底病害进行研究,通过泄压、注浆加固、结构及道床拆换等方式进行专项治理,取得了成效,保障了铁路的正常运行。
With the project for the treatment of the damage and defects of the Wuyanhe Tunnel of the Mid-South Passage Railway(the Wa-Ri Railway)as the engineering background,in the present paper a detailed study is made of the damage and defects of the tunel base resulting from underground water,loose dregs at the bottom,weak surrounding rock,earth stress and the like.Through the technical measures of releasing pressure,grouting for reinforcment,changing structures and track beds,and the like,the damaged sections and defects of the base of the tunnel are especially treated,with good engineering effects achieved,and the normal operation of the railways ensured.
