摘　　要：运用FEFLOW有限元地下水模拟软件,对某条件下地下水环境进行了评价研究。根据水文地质条件、地质条件,建立了数学模型以及水文地质概念模型,利用FEFLOW数值模拟软件研究了地下水流场、分层的均衡性、潜水埋深、潜水水位,研究得出:在矿井开采与某水源开采的条件下,形成了以某水源地为中心的大范围降落漏斗,从而造成潜水位下降程度相近;矿井抽水造成的潜水位下降和水源地抽水影响相比并不明显;2种方式的开采造成潜水埋深大幅度增加,导致了评价区域内潜水获得的蒸发量和大气降水入渗补给量明显降低,研究为类似工程条件下地下水环境影响评价提供一定的借鉴意义。In order to evaluate the groundwater environment under certain conditions,the groundwater simulation software FEFLOW was used to establish the mathematical model and the conceptual model of hydrogeology according to the hydrogeological conditions and geological conditions.The groundwater flow field was studied using FEFLOW numerical simulation software.Layer balance,diving depth and diving water level.The study showed that under the conditions of mining and a water source mining,a large-scale descending funnel with a water source as the center has been formed,resulting in the similar decrease of the diving potential;the decrease of the submersible water level caused by pumping was not obvious compared with that of water pumping.The two kinds of mining methods resulted in a significant increase of the buried depth of the submerged water,resulting in a significant decrease of the evaporation of the submersible and the infiltration recharge of the precipitation in the evaluation area.The research provided some references for the environmental impact assessment of groundwater under similar engineering conditions.
