摘要 地下水是可开采水资源的重要组成部分,是重要的生态因子。目前解决地下水流和溶质运移问题最主要的方法是有限差分法和有限元法,这两种方法都有各自的程序可以用于饱和—非饱和渗流计算,采用有限元法,对隧洞开挖过程中地下水水位流场变化进行预测并分析,评价其对地下水环境的影响,为水电站引水隧洞工程地下水环境影响评价方法提供了参考。 Groundwater is an important part of recoverable water resources and an important ecological factor. At present,the most important methods to solve the problem of groundwater flow and solute transport are the finite difference method and the finite element method, both of which have their own programs that can be used for saturation-unsaturated seepage calculation. In this paper, the finite element method is adopted. The change of groundwater level flow field during tunnel excavation is predicted and analyzed,and its influence on groundwater environment is evaluated. It provides a reference for the groundwater environmental impact assessment method of the diversion tunnel project of hydropower station.
