摘　　要：随着经济社会的快速发展,我国地下水开发利用量持续快速增长,超采地下水造成的水位下降、地面沉降等问题逐渐突显,揭示地下水流场变化规律对地下水开采方案的制定具有重要理论指导意义。因此,本文以青岛平度市为研究背景,统筹考虑区域性地形地貌、地质结构、地质单元特征等要素,建立研究区地下水流场数值模型,并开展不同地下水开采方案下的地下水流场动态演化趋势预测分析。结果表明:以2022年为现状条件开采地下水,10年后水位将下降5 m左右。随着开采强度的降低,水位下降的速度逐渐减小,当开采量减少30%的条件下,10年后水位下降2.8 m左右。Accompanying with rapid development of economy and society,groundwater development and utilization has been continued to grow rapidly in our country,the water level decline caused by overexploitation of groundwater,the land settlement and other problems gradually became more and more obviously,and the change law of underground water flow field has an important theoretical significance for the formulation of groundwater mining plan.In this paper,taking Pingdu city in Qingdao city as the research background,considering regional topography,geological structures,geological unit characteristics and other factors,a numerical model of the groundwater flow field in the study area has been established,and the prediction and analysis of the dynamic evolution trend of the groundwater flow field under different groundwater exploitation schemes have been carried out.It is showed that if groundwater is mined in 2022,the water level will decrease by about 5m after 10 years.Accompanying with the reduction of mining intensity,the speed of water level decline gradually decreases.When the mining volume is reduced by 30%,the water level drops about 2.8m after 10 years.
