地下水超采区混合井回灌流量计算与效率分析
Analysis on artificial supply discharge and efficiency of mix-well in excessively pumping area
【摘要】 以试验数据为基础,对地下水超采区混合井回灌过程中井流量计算的方法进行理论归类,发现混合井回灌过程中的井流计算方法一般可按承压水井流计算方法进行;定量分析混合井单位流量变化过程,发现其回灌效率大于抽水效率;利用Grapher系统对不同流量回灌过程进行分析,得出利用混合井在超采区实施回灌其效率开始时虽存在衰减,但最终会趋于稳定。停灌后回灌井水位在数小时恢复到初始水位,说明回灌过程对开采井的滤水结构影响不大,管井水力传导仍然良好。
【Abstract】 based on the test,the mix-well flow calculation is classified during artificial supply to the over pumping area.The mix-well flow variational process is quantitatively analyzed,including the artificial supply efficiency.The artificial supply process is analyzed using Grapher sysytem. It is found that it existed an attenuation during artificial supply process by using mix-well in the over pumping area,which finally tended to stabilization.There was also silt by using eau douce to artificial supply.The research experience can be extended to solve the same problem occurring in cities and irrigation areas.
【Key words】 Mix-well flow artificial supply test; well-flow calculation classifying; artificial supply process analyze; artificial supply efficiency;
