摘　　要：针对中国黄泛平原井灌地区地下水超采引起的大面积地下水漏斗问题,选择山东省临清市项目区,利用土壤水动力学、水力学和地下水动力学等相关理论,实施了地下水回灌工程对技术方案和参数进行设计,计算其回灌效果。通过计算结果可知,该回灌工程在7 d的引水过程中,增加了52 310.82 m^3的地下水补给量,占地下水补给总量的60.7%。野外回灌系统流速监测和示踪试验表明,该工程设计方案可行。在原沟渠渗入补给的基础上,该种明沟—暗管—竖井回灌补源工程增加了地下水补给量,对地下水漏斗恢复和旱涝碱综合治理具有重要作用。Aiming at the problem of groundwater depression cone with large area caused by the over-exploitation of groundwater within the well irrigation area in the Yellow River Flood Plain in China, a groundwater recharge project in Linqing of Shandong Province is selected for calculating the effect of the water recharge in the area, for which the relevant theories, i. e. soil hydrody- namics, hydraulics and groundwater dynamics, are applied to design the technical scheme and the paramers concerned. It is known form the calculation that the groundwater recharge is increasd by 52 310. 82 m3during the water diversion of 7d from that groundwater recharge project, which is about 60. 7% of the total groundwater recharge therein. The field flow rate monitoring for the water recharge system and the relevant tracing test show that the design scheme of the project is feasible. Based on the infil- tration recharge from the original irrigation canals and ditches therein, the groundwater recharge project with open ditch, buried perforated pipe and shaft increases the groundwater recharge, which has an important effect on the restoration of groundwater fun- nel and the comprehensive improvement of drought, waterlogging, salinization.
