摘　　要：通过采用水均衡法计算了滹沱河入渗试验期间的河道入渗补给量,并求取了滹沱河水源地一带获得的河道入渗补给量。研究表明:试验期间河道入渗水量为1 482.75万m3,河道入渗补给地下水量为1 382.89万m3,河道渗漏补给系数为93%;滹沱河水源地接受的补给量为742.53万m3,水源地范围内的观测井最大水位上升幅度6.823m,地下水补给效果明显。Water balance method was applied to calculate recharge from river water infiltration during a large infiltration test in the Hutuo River, and especially to calculate the infiltrating recharge in the water source area. The results showed that the amount of river infiltration water is 14 827 500 m3 during the test, and groundwater recharge from river infiltration water is 13 828 900 m3. The groundwater recharge coefficient from river infiltration is 93%. The amount of received water in the water source area is 7 425 300 m3. Meanwhile, the maximum rising magnitude of groundwater level in the observation wells located in the water source area is 6. 823 m, indicating apparent groundwater recharge effects.
