| 隧道涌水严重影响其施工及后期运营安全。夜珠坪隧道在施工期间发生了较严重的涌水，结合隧道实际涌水情况，通过对隧址地形地貌、地质、地层岩性及洞内探孔情况的综合分析，分析了隧道涌水的原因，有针对性的提出隧道涌水总体设计方案和施工设计方案，并给出了相应的质量安全保证措施。隧道注浆与未注浆相比，初支周边围岩的渗水流速有了质的改善，注浆效果明显，改变了岩体的力学特性，提高了其抵抗变形的能力，隧道发生大范围涌水的概率急剧减小，说明注浆对涌水的预防和治理起到极其重要的作用。 |

| Tunnel gushing water seriously affects the construction and operational safety of the later period. During the construction period, there was more serious gushing water during the construction. Combined with the actual gushing of the tunnel, the causes of tunnel gushing were analyzed through the comprehensive analysis of topography, geology, lithology of the tunnels and the holes in the tunnel. Proposed the overall design of tunnel gushing water and construction design, and gives the corresponding quality and safety assurance measures.Compared with un-grouting, the water seepage velocity of surrounding rock of initial branch has been improved by tunnel grouting, the effect of grouting is obvious, the mechanical properties of rock mass are changed and its resistance to deformation is improved. The probability of abrupt decrease, indicating grouting on the prevention and treatment of gushing water plays an extremely important role. |
