GMS在地下水数值模拟中的应用——以云南文山州某水库为例

The Application of GMS in Groundwater Numerical Simulation

地下水数值模拟是预测、评价地下水资源环境问题的常用方法,为具体水文地质问题的解决提供良好依据.GMS作为地下水模拟软件中的代表,模拟应用十分广泛.根据云南文山州某水库建设项目水文地质条件,主要运用渗透系数分区及三维渗透张量的方式对含水层各向异性渗透性进行表征,应用GMS进行地下水流场模拟,分析了水库建设对流域内地下水流场的影响,为裂隙岩溶水数值模拟研究提供一定依据.

Groundwater numerical simulation is a common method to predict and evaluate the groundwater resourcesand environmental problems,which provides a good basis for resolving the specific hydrogeological problems.As a typical representative among those groundwater simulation softwares,GMS has been used widely. According tothe hydrogeological conditions of the reservoir construction project which is located in Wenshan of YunnanProvince,the aquifer permeability anisotropy is characterized by using the main way of partition of the coefficientsof permeability and three-dimensional way of permeability tensor. The impact on the groundwater flow field in thebasin caused by reservoir construction is analyzed by the groundwater flow field simulation which is the applicationof GMS. The study provides reference for fissure karst water numerical simulation study.
