| 摘 要： | 隧道穿越既有富水采空区综合施工技术是隧道建设中面临的特殊工程问题,目前我国采空区隧道建设技术尚处于摸索阶段。以在建重庆万(州)—开(县)高速公路铁峰山2号隧道为依托工程,对隧道穿越顶部富水采空区洞段,采用超前预注浆止水、周边径向注浆堵水等治水方法,堵排结合,有效地控制了隧道施工中涌水等现象,保证了隧道施工安全顺利进行。该隧道的施工经验可为同类工程的施工提供有益的借鉴和参考。

| Abstract: | The comprehensive construction technique for the tunnel passing through a already-existing depletion region being rich in water is a special engineering problem in .tunnel construction, and this technique is still in a grouping stage. I the construction of Tiefengshan No. 2 tunnel of Wanzhou-kalxlan Expressway in Chongqing, this comprehensive construetion technique is used in the tunnel section of the depletion region, including such the methods as stopping water by pregrouting and ponding water by radial grouting and so on, so that the seepage water is controlled effeclively to guarantee the safety in the tunnel construction. The construction experiences in this tunnel may provide some references for similar projects. |
