| 摘 要： | 利用抽水井群和注水井群可以控制生态围垦区的地下水位.研究了潜水抽-注水井(群)耦合作用下浸润线的求解方法,利用势流理论和镜像原理,在假定含水层水平及土层渗透系数各向同性的条件下,推导出完整抽-注水井(群)耦合作用时浸润线的计算公式及非完整抽-注水井(群)耦合作用时浸润线的计算公式,还对潜水单个非完整抽水井及非完整抽-注水井群耦合作用时的解析解和数值解作了比较,结果表明,两者吻合得较好.同时还给出该理论用于地下水位控制中求解抽水量和注水量的方法等,对工程设计有实用价值. |

| Abstract: | A method for solving the seepage line under the coupled action of pumping-recharging well(group) was developed.On the condition of the aquifer was horizontal and the permeability coefficient is isotropic,the analytical formula for solving the seepage line under the coupled action of fully pumping-recharging well(group) and partially pumping-recharging well(group) are derived based on the potential flow theory and the image principle.A contrast between analytical result and numerical result is presented for one partially penetrating well and pumping-recharging well(group),it shows both of the value are in a good agreement.Finally the method for solving the quantity of pumping and recharging is given. |
| Keywords: | ecological retaining polder recharge well group seepage line partially penetrating well |
