周期性开采和回灌条件下浅层地下水位变化特征研究——以天津滨海新区为例
发布时间：2018-10-11 07:56
【摘要】：针对天津滨海新区进行的周期性抽水与回灌试验,根据抽水试验计算了含水层的渗透系数和抽水的影响范围,并据此分析了抽水与回灌试验的叠加效应;根据实测数据分析了抽水回灌周期、流量、不同采灌方式等因素对地下水位埋深的影响。不论是连续式还是间歇式的周期性抽水与回灌方式,产生的地面沉降量都很小,并且间歇式周期性抽水回灌方式优于连续式周期性抽水回灌方式。试验结果表明采用周期性抽水与回灌的方法建立人工渗流场可有效减小地源热泵工程中的地面沉降。
[Abstract]:In view of the periodic pumping and recharging tests carried out in Tianjin Binhai New area, the permeability coefficient of the aquifer and the influence range of the pumping water are calculated according to the pumping test, and the superposition effect between the pumping and the recharging test is analyzed. Based on the measured data, the effects of pumping water recharge period, discharge and different mining and irrigation methods on the buried depth of groundwater table are analyzed. Both continuous and intermittent periodic pumping and recharging methods produce a small amount of land subsidence, and the intermittent periodic pumping and recharging methods are superior to the continuous periodic pumping and recharging methods. The experimental results show that the establishment of artificial seepage field by periodic pumping and recharging can effectively reduce the ground subsidence in the ground source heat pump project.
