摘　　要：水库渗漏补给是泉域复流的重要形式,确定水库渗漏量及影响因素对于预测泉域复流很有必要。以三泉水库为例,运用地下水模拟软件GMS中的Modflow和LAK3程序包,建立水库和地下水含水层耦合模型,模拟预测不同关井压采方案对水库渗漏量及古堆泉口水位的影响程度,并结合正交试验选取渗漏区域的垂向渗透系数、平均渗透性能、给水度和贮水系数进行参数敏感性分析。结果表明:实施关井压采后,水库渗漏量增加,泉口水位恢复加快,对渗漏量的影响大小顺序为平均渗透性能>给水度>垂向渗透系数>贮水系数。Reservoir leakage has become an important form of spring reflow , so it is necessary to determine the quantity of reservoir leakage and the influencing factors for the study of spring reflow. Taking Sanquan Reservoir as an object study , a model coupling reservoir and groundwater based on Modflow and LAK3 packages in GMS was built to predict the reservoir leakage and the water level of Gudui Spring vent. Then sensitivity analysis was performed by vertical permeability coefficient , lake leakance , specific yield and storativity. The results of nu-merical simulation show that after measures of shutin and compress groundwater are applied , the quantity of reservoir leakage is increased , and the water level of the spring vent recovery is speeded up. The result of sensitivity analysis shows that the factors influencing of leakage fol-low the descending order of lake leakance , specific yield , vertical permeability coefficient and storativity.
