摘　　要：在对黄河海勃湾水利枢纽水文地质条件分析的基础上,利用Modflow软件建立东岸近坝区地下水数值模拟模型,并对渗流场进行三维数值模拟计算。通过多次调试和拟合,计算区的初始渗流场和实测的初始渗流基本一致,并以此对水库正常蓄水后的地下水渗流场进行模拟预测。结果表明,当水库蓄水后,东岸近坝区地下水渗流场发生较大变化,东岸坝肩存在明显绕坝渗漏现象。该研究成果为评价地下水位抬升对近坝区的影响提供了重要依据。Based on the analysis of the Yellow River Bohai bay water conservancy hydro-geological conditions,set up the east coast near the dam area of groundwater numerical simulation model by using Modflow software,and the seepage field in three-dimensional numerical simulation.After many times of debugging and fitting,the initial seepage field of the calculated area is basically consistent with the measured initial seepage,and the groundwater seepage field after reservoir normal storage is simulated and predicted.The results show that the groundwater seepage field on the east bank has changed greatly after the reservoir storage,and the dam abutment has obvious seepage around the dam.The research results provide an important basis for the evaluation of the influence of the uplift of the groundwater table on the near dam area.
