摘要
根据平阴县前寨—凌庄水源地的水文地质条件,建立了裂隙岩溶水的平面二维非稳定地下水流模型,并应用Modflow软件对该区地下水流进行数值模拟。在进行计算区剖分、空间离散、参数分区、边界条件及源汇项处理与模型识别、验证的基础上,通过预测分析得出:该水源地按设计开采量开采后,地下水位不会出现持续下降趋势,最大降深在允许范围之内,因而也不会诱发环境地质问题。
According to hydro - geological condition of Qianzhai - Lingzhuang water source, two - dimensional un- stable groundwater flow model of fracture - karst water is set up. By using modflow software, numerical simulation of groundwater flow in this area is carried out. On the basis of calculating the area subdivision, spatial dispersion, geographical parameters, boundary conditions and sources conduction, model recognition and identification, after the predication and analysis, it is regarded that the groundwater level will not declining continuously after the min- ing exploitation according to the design. The largest declining depth will be kept within the permitted scope. Thus, it will not cause environmental geological problems.
