摘要
由于铁路隧道的施工,地下水进入隧道,形成了新的排泄基准面,对区域地下水环境产生较大影响,故对该类问题进行深入研究具有重要的工程实践意义。以中坝岩溶隧道为例,采用Visual modflow对中坝隧道进行三维数值模拟,模拟中坝隧道开挖建设后,地下分水岭的演化过程,以此来探讨分析其对地下水环境的影响。
As tunnel construction will change groundwater flow and form a new groundwater base -level which will affect groundwater environment dramatically, it is of great practical interest to study on how tunnel construction affect groundwater environ-mental variation. By using Visual modflow, the paper makes a 3D numerical simulation of the groundwater watershed evolution dur-ing the construction of Zhongba Tunnel and analysis the relation between tunnel construction and groundwater environment.
