二郎山特长隧道施工对地下水环境的影响

摘要

The influence of Erlang mountain tunnel construction on the regional groundwater environment was analyzed based on Erlang mountain region hydrogeological characteristics to provide support for Erlang mountain tunnel groundwater environment special investigation and protection work in the next phase. The results showed that normal tunnel water inflow is 34 321.62 m3/d, and water inflow is 6400 m3/d after taking appropriate measures; Erlang mountain tunnel construction has some impacts on the groundwater system of the tunnel site, but the scope of impacts is low and controllable.%　　结合二郎山区域水文地质特点,分析了二郎山特长隧道施工对区域地下水环境的影响,为下阶段开展二郎山特长隧道地下水环境专项调查与保护工作提供支撑.结果表明,隧道正常涌水量为34321.62 m3/d,采取相应措施后用水量为6400 m3/d.二郎山特长隧道施工对隧址区地下水系统有一定的影响,但影响范围较小、可控.
