摘　　要：为解决沙漠低渗透地区雨水自然下渗速度慢的问题,通过布设回灌井来加速雨水收集池中雨水的渗透速率,达到快速下渗的目的,利用数值模拟法和现场回灌试验相结合,计算单个雨水收集池所需回灌井的数量、间距以及回灌井的排列方式,确定了一种适用于沙漠低渗透地区回灌井的下渗方案。通过实例计算,该回灌井的下渗方案能有效满足沙漠地区的雨水回灌要求,具有一定的工程指导意义。In order to solve the problem of slow natural infiltration of rainwater in low permeability desert areas,the infiltration rate of rainwater in rainwater collection tanks is accelerated by setting reinjection wells to achieve the goal of rapid infiltration.The number,spacing and arrangement of reinjection wells required for a single rainwater collection tank are calculated by using numerical simulation method and on-site reinjection test,and an infiltration scheme suitable for reinjection wells in low permeability desert areas is determined.Through the example calculation,the infiltration scheme of the reinjection well can effectively meet the requirements of rainwater reinjection in desert areas,and has certain engineering significance.
