[目的] 基于灌区已建成“井电双控”平台的优势,提出利用抽水井水位来获取开采期地下水流场的动态变化,为地下水资源的科学管理及合理利用提供技术支撑。[方法] 利用Processing MODFLOW软件模拟得出研究区的仿真流场,以此作为抽水井水位确定流场的判别标准,并对该方法下流场的拟合效果进行评价与改进。[结果] 直接使用抽水井水位得出的流场较仿真流场整体偏小;使用抽水井降深修正后的水位得出的流场与仿真流场拟合效果较好,但实际中需要结合模型计算;在部分抽水井内安装水位监测设备基础上增加专用监测井,其得到的动态流场与仿真流场接近且易于实现,说明该方法可用于研究区流场的动态监测。[结论] 基于“井电双控”系统下,将抽水井作为监测井的方法有效解决了因地下水监测站网密度低、信息传输时效性差等造成对地下水管理存在偏差的问题,对加强地下水位—水量的双控管理及区域地下水资源的保护具有一定的应用价值。
[Objective] Based on the advantages of the "well and electricity dual control" platform that has been built in the irrigation area
the dynamic changes of the groundwater flow field during the mining period were obtained by using the water level of the pumping well
in order to provide technical support for the scientific management and rational utilization of groundwater resources.[Methods] Using Processing MODFLOW software to simulate the simulated flow field in the study area
and taking it as the criterion for determining the flow field of the pumping well water level
the fitting effect of the flow field was evaluated and improved.[Results] The flow field obtained by directly using the water level of the pumping well was smaller than the simulation flow field. The flow field obtained by using the water level after the corrected drawdown of the pumping well had a good fitting effect with the simulated flow field
but it should be calculated in combination with the model in practice. The dynamic flow field obtained was close to the simulated flow field and was easy to implement by installing water level monitoring equipment in some pumping wells and adding special monitoring wells
indicating that the method could be used for dynamic monitoring of the flow field in the study area.[Conclusion] The proposed method of using pumping wells as monitoring wells based on the "well and electricity dual control" system effectively can solve the problem of deviations in groundwater management caused by the low density of groundwater monitoring stations and poor information transmission timeliness. It has certain application value for strengthening the dual control management of groundwater level and water volume and the protection of regional groundwater resources.
