摘要
以北京市某地铁隧道错台变形治理为工程背景,对复合式注浆施工技术加以研究,对隧道注浆前和注浆后分别进行了监控量测。根据工后地质钻孔和实测数据,隧道及道床结构沉降基本稳定;隧道管片裂缝及错台现象有所缓解。证明复合式注浆技术作为一种洞外处理隧道沉降、变形等病害的治理手段,可供借鉴。
Taking the deformation control of a certain subway tunnel in Beijing as engineering background,the composite grouting construction technology is studied,and the monitoring measurement is carried out before and after the tunnel grouting in this paper. According to the geological drilling data and measured data,the settlement of tunnel and track bed structure is basically stable,on the other side,tunnel segment cracks and the phenomenon of staggered platform has been alleviated. It is proved that the compound grouting technique can be used as a treatment method for tunnel settlement,deformation and other diseases.
