Study on numerical simulation of seepage movement in underground reservoir backfiltration well

以地下水库反滤回灌井为研究对象,利用ADINA水工数理计算系统,以有限元数理模拟计算的方式,对地下水库反滤回灌井渗流移位规律开展专题计算分析,结果可知:在回灌过程中,地下水含水层系统中,水位与回灌量呈显著线性关系。在抽水井附近区域,地面降沉最为显著,表现出明显的曲线分布状态。通过采用在抽水井附近搭建回灌井,可避免地下水头持续降低,形成平衡渗流场,控制地面沉降影响范围。该计算分析形式和规律揭示成果可为同类水工计算和工程应用提供研究和技术参考。

Based on the underground reservoir filter injection Wells as the research object,using the scaled hydraulic adina. the mathematical calculation system,by way of finite element calculation of mathematical simulation,the underground reservoir seepage shift law filter recharge well to carry out the project calculation and analysis results indicate: in the process of injection,the aquifer system,groundwater level and recharge quantity has significant linear relationship in the neighborhood of pumping Wells,the ground sink down most significantly,the curve of the apparent distribution by adopting the pumping well built near the injection Wells,can avoid decreasing groundwater head,balances the seepage field,influence scope of ground subsidence controlThe results of the calculation and analysis form and law can provide research and technical reference for similar hydraulic calculation and engineering application.
