Water Gushing Treatment Technique for Zhongtianshan Tunnel

中天山隧道特大高压涌水段具有水头压力大、持续时间长、涌水量大的特点;文章研究了涌水产生的机理,制定并实施了泄水减压结合帷幕注浆堵水的施工方案,快速有效地通过了特大高压涌水地质灾害洞段,效果显著。

Zhongtianshan tunnel＇s high pressure water gushing section had unique features such as high pressure at water head, long duration period and large gushing amount. This article probed into the generation mechanism of water gushing and drew up a feasible construction plan for water plugging by combining the efforts of draining and curtain grouting. This plan was applied to the construction of Zhongtianshan tunnel＇s high pressure water gushing section effectively. As a result, the construction was completed smoothly and a remarkable result was reached.
