摘要
水跃值的变化比较复杂,与抽水井深度、半径、井出水量以及抽水持续时间等因素有关,其中井出水量影响最大。本文根据抽水试验资料总结了黄土潜水井水跃值的变化规律并分析了其成因;总结了水位降深随抽水时间的变化关系,并建立了经验公式;提出了公式中参数的确定方法。
Connected by the depth, radius, water yield, pumping time of the well, the hydraulic jump varied complexly. Based on data of pumping test, this paper summarized the variational law of well in phreatic aquifer of loess and the diversified relationship between water table and pumping time. It also showed the empirical formula and put forward the method of confirming parameter in the expressions.
