秦岭某高速公路隧道涌水原因分析及治理方案

Cause analysis and control scheme of tunnel gushing in Qinling expressway

隧道涌水严重影响施工及后期的运营安全。秦岭某隧道在施工期间发生了较严重的涌水现象,通过对隧址地形地貌、地质、地层岩性及涌水特点、初支开裂情况、洞内钻孔情况的综合分析,研究隧道涌水的原因和机制,并提出行之有效的涌水治理方案。

The tunnel gushing water seriously affects the construction and the later operation safety. A serious water gushing phenomenon occurred during the construction of a tunnel in Qinling Mountain,through the comprehensive analysis of the topography,geology,stratigraphic lithology and water inrush characteristics,initial branch cracking and borehole bore,the paper studies the cause and mechanism of water gushing in tunnels,and puts forward the effective water inrush treatment plan.
