【摘要】：針對中國黃泛平原井灌地區(qū)地下水超采引起的大面積地下水漏斗問題,選擇山東省臨清市項(xiàng)目區(qū),利用土壤水動(dòng)力學(xué)、水力學(xué)和地下水動(dòng)力學(xué)等相關(guān)理論,實(shí)施了地下水回灌工程對技術(shù)方案和參數(shù)進(jìn)行設(shè)計(jì),計(jì)算其回灌效果。通過計(jì)算結(jié)果可知,該回灌工程在7 d的引水過程中,增加了52 310.82 m~3的地下水補(bǔ)給量,占地下水補(bǔ)給總量的60.7%。野外回灌系統(tǒng)流速監(jiān)測和示蹤試驗(yàn)表明,該工程設(shè)計(jì)方案可行。在原溝渠滲入補(bǔ)給的基礎(chǔ)上,該種明溝—暗管—豎井回灌補(bǔ)源工程增加了地下水補(bǔ)給量,對地下水漏斗恢復(fù)和旱澇堿綜合治理具有重要作用。
[Abstract]:Aiming at the problem of large area groundwater funnel caused by overexploitation of groundwater in well irrigation area of Yellow River Plain in China, the project area of Linqing City, Shandong Province, is selected to utilize the relevant theories such as soil hydrodynamics, hydraulics and groundwater dynamics, etc. The technical scheme and parameters of groundwater recharge project were designed and the recharge effect was calculated. The calculation results show that the recharge project increased the groundwater supply by 52 310.82 mm3 during the 7 d diversion process, accounting for 60.7% of the total groundwater recharge. Field recharge system velocity monitoring and tracer test show that the project design is feasible. On the basis of infiltration and recharge of the original ditch, the project of recharge and recharge of the Ming ditch, the hidden pipe and the vertical well increases the groundwater supply, and plays an important role in the recovery of groundwater funnel and the comprehensive treatment of drought, waterlogging and alkali.
