摘　　要：平原区水库蓄水后,绕坝渗流改变了大坝下游地下水的补排关系,会引起大坝上下游一定范围内的地下水位抬升,对紧邻坝区的居民建筑物产生影响。以海勃湾水库为例,利用Visual Modflow建立海勃湾城区三维地质模型,并对模型中的地质参数和模型的边界范围进行反演,反演结果表明地质参数和模型边界识别合理。利用该数值模型模拟海勃湾水库蓄水后近坝区地下水渗流场,为评价水库建成后地下水位抬升对近坝区的影响提供依据,分析水库环境地质问题影响范围,进而科学指导海勃湾滨库区的规划布局。After the impoundment of reservoir in plain area,the seepage around the dam changes the relationship between the recharge and discharge of groundwater,resulting in the water table rise in a certain scope and instability of residential buildings adjacent to the dam.Visual Modflow is used to establish the 3D geological model of Haibowan Reservoir area,and the parameters and boundary of the model are inversed.The inversion results indicate that the geological parameters and the model boundary condition are reasonable.The groundwater seepage field after impoundment is simulated by the model,which provides the basis for evaluating the impact of groundwater rise after impoundment; the range of environmental and geological influence is analyzed to further provide guidelines for planning of Haibowan Reservoir area.
