摘要： 达坂隧洞线路全长31.92 km，沿线穿越多处膨胀岩、泥质粉砂岩等不良地质洞段，施工中多次发生卡机事故并成功脱困，对其回填灌浆、固结灌浆和帷幕灌浆技术进行了系统总结，对于同类工程施工具有较强的借鉴意义。

关键词: 卡机, 回填灌浆, 固结灌浆, 帷幕灌浆

Abstract: The Daban diversion tunnel has a total length of 31.92km. This tunnel crosses many poor geological areas, such as, expansive rock mass, clayey silty fine sandstone rock masses. The Tunnel Boring Machines (TBM) was jammed and successfully remediated several times during the tunnel excavation. This paper summarizes various grouting methods that are applied in the tunnel excavation, such as, gravity grout, compaction grout and seepage cutoff grout.
