【摘要】:針對(duì)天津?yàn)I海新區(qū)進(jìn)行的周期性抽水與回灌試驗(yàn),根據(jù)抽水試驗(yàn)計(jì)算了含水層的滲透系數(shù)和抽水的影響范圍,并據(jù)此分析了抽水與回灌試驗(yàn)的疊加效應(yīng);根據(jù)實(shí)測數(shù)據(jù)分析了抽水回灌周期、流量、不同采灌方式等因素對(duì)地下水位埋深的影響。不論是連續(xù)式還是間歇式的周期性抽水與回灌方式,產(chǎn)生的地面沉降量都很小,并且間歇式周期性抽水回灌方式優(yōu)于連續(xù)式周期性抽水回灌方式。試驗(yàn)結(jié)果表明采用周期性抽水與回灌的方法建立人工滲流場可有效減小地源熱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.
