以Darcy定律为基础,区分泥沙的渗透系数与地层的渗透系数相当或者相差较大、渗透层为均质或者为层状几种情况,分别推导出浑水渗流时计算渗流量的积分方程和微分方程,给出了求解这些浑水渗流微分方程的差分格式.石嘴山市在全国首次开展利用电厂冷却尾水进行深层回灌回采试验,利用本文方法研究了回灌试验场冷却水浑水回灌时,地表泥沙的淤积规律,入渗量随时间的变化规律,并预测了回灌影响下地下水位随时间的变化规律.
Based on Darcy’s law, the permeability coefficient of sediment is equal or different from the permeability coefficient of the formation, and the permeation layer is homogeneous or layered. Integral equations to calculate seepage flow are derived respectively Differential equations are given to solve the differential equations of muddy water seepage differential equations Shizuishan city in the country for the first time using the power plant cooling tailings for deep recharge back to the mining experiment using the method to study the test site recirculation of cooling water muddy water , The siltation of sediment on the surface and the law of infiltration volume change with time, and predicts the variation of groundwater level with time under the influence of recharge.
