摘要
深埋隧道涌突水对工程施工及区域环境都有很重要的影响 ,笔者通过圆梁山隧道毛坝向斜段涌突水监测数据 ,结合地表降水资料 ,分析了影响隧道排水量、隧道支护稳定性的主要自然因素及排水工程 ,对地表水环境产生的影响。监测和分析认为 ,隧道揭露的含水溶洞突水对当地水环境影响最大 ,也是地表降水对隧道支护产生影响的主要通道。
Water gushing from deep-buried and long tunnel has great influence upon the tunnel construction and local environment. Referring to the monitored data of gushing water and the rainfall above Yuanliangshan tunnel in Maoba syncline,the factors influencing the capacity of water drainage,the stability of tunnel support, and environment of surface water were analyzed. It was found that the water gushing from the water filled limestone cave contributes the great impact on water environment,which is also the main passage for surface water to influence the stability of the tunnel support.
