摘　　要：根据天津滨海地区浅层地下水特征及区域地质特征,建立了浅层地下水综合循环利用储能的抽灌系统及地层竖向位移监测系统,在系统运行期对地层变形进行了长期监测。根据监测资料,对浅层地下水抽灌循环利用过程中引发的地层竖向位移进行了相应研究,探明了发生沉降的主要层位有含水层及浅部欠固结软土,同时也证实了通过抽灌结合的地下水利用方式对地面沉降起到了一定的缓减作用。According to the characteristics of shallow groundwater and regional geological characteristics of Tianjin coastal area, this article establishes the energy pumping and recharging system of synthetically recycling stored energy of shallow groundwater and the monitoring system of strata vertical displacement. Moreover, it did long - term monitoring for stratum deformation during the system running period. According to the monitoring data, the article makes the corresponding researches on vertical displacements of strata which are caused by shallow groundwater pumping and recharging circulating utilization. And then it discovers the main settlement strata are shallow aquifer and underconsolidated soft soil, and also proves that the circulating utilization of groundwater has mitigation effects on ~round subsidence.
