摘要
针对人工回灌过程中的悬浮物堵塞问题,利用三组不同悬浮物浓度的回灌水做了室内砂柱回灌试验,分析了回灌过程中试管砂柱侧壁不同位置处测压管水头、底部出流速率、砂样不同位置处的渗透系数、试样顶部悬浮物沉积等变化规律,得到了一些有益的结论,可为地下水人工回灌设计提供参考依据。
Aiming at the problems of suspended solid blockage in process of groundwater artificial recharge,sand column recharge model with three groups of different concentration recharge water is built.The variation rules of piezometer head in different position,outflow velocity at the bottom of sand column,permeability coefficient in different position of sand column and suspended solid deposition at the top of sample are analyzed.Finally,some useful conclusions are obtained,which provides reference for design of groundwater artificial recharge.
