通过分析隧道塌方原因,结合工程具体情况,采用小导管预注浆加固塌方区,处理后并加强监测。从隧道拱顶下沉和周边收敛得到的结果可知,其变形在允许的范围内,小导管预注浆处理塌方区取得了良好效果。
通過分析隧道塌方原因,結閤工程具體情況,採用小導管預註漿加固塌方區,處理後併加彊鑑測。從隧道拱頂下沉和週邊收斂得到的結果可知,其變形在允許的範圍內,小導管預註漿處理塌方區取得瞭良好效果。

According to the analysis of reasons for the tunnel collapses, the paper adopts the small duet pre-grouting to consolidation the collapsing zones by combining with facts in projects, strengthens the inspection after the treatment, and proves by the results of the settlement of the tunnel vault and the surrounding convergence that the deformation is controlled within the permitted range, and the small duet pre-grouting at the collapsing zones achieves better effect.
