木寨岭隧道涌水预测及地下水环境影响分析

Study on the influence of the construction of Muzhailing tunnel on groundwater environment

我国西北干旱半干旱地区,由于干旱少雨、森林覆盖率极低、自然资源贫瘠、区域地形地貌等因素的限制,长期处于经济欠发达状态。铁路工程及隧道工程建设在带动地区经济发展的同时,不可避免地对环境产生了一定影响。本文以甘肃木寨岭隧道建设为实例,通过对隧道涌水来源及涌水量预测计算,分析隧道建设对地下水环境的影响,并就相关问题进行了探讨,确保将隧道建设对地下水环境的影响降至最低。

The arid and semi-arid regions of northwestern China have been economically underdeveloped for a long time due to the drought,the lack of rainfall and the particular geomorphological features.Railway engineering and tunnel construction can promote the regional development of economy,but inevitably have an impact on the environment.This paper studied the example of the Muzhailing Tunnel in Gansu Province.The water source and water inflow from the tunnel were predicted then utilized to analyze the impacts of tunnel construction on the groundwater environment.Further related issues were discussed to ensure the minimum impacts on the groundwater environment.
