| 摘 要： | 明月山隧道水文地质条件复杂,岩溶地下水发育,施工过程中发生大的涌突水,掌子面最大流量达15万m3/d。设计采用先在突水点设止浆墙,然后再对前方围岩进行全断面深孔预注浆进行堵水,施工实践表明该处理方式是成功的,目前,隧道施工已顺利通过突水地段。本次注浆堵水的成功为隧道涌突水的处理积累了经验,可供类似工程借鉴与参考。

| Abstract: | Hydrogeologic conditions are complicated in Mingyueshan Tunnel on Dianlin Highway,karst and groundwater are developed.Groundwater flushed heavily in the course of construction,the maximum inflow rate reaches 150 000 m3/d.The design plan is that preventing-grout wall is constructed at the point of swelling earlier and full-face curtain grouting is brought into effect for the forward surrounding wall.The construction pratice indicates that the design plan is successful.The construction of the tunnel has passed successfully the swelling place.The experiences of the swelling disposal provide the reference for the analogous engineering. |
