| 摘 要： | 人工回灌是提高水资源利用水平的重要工程措施。深入研究渗滤池回灌过程机理,基于Hydrus-2D,结合具体渗滤池回灌算例,建立渗滤池回灌的二维饱和-非饱和渗流数值模型。模拟结果表明：回灌水入渗形成的＂湿润峰＂逐渐向饱和带移动,同时饱和带的浸润线逐渐上升,形成不断扩大的饱和区,直到形成一个连续的饱和带。回灌水出流速率经过了迅速增大到一峰值后快速减小,然后又缓慢变小的过程,回灌水入渗速率随时间变化的这一特征与Green-Ampt入渗模型的结论是一致的。

| Abstract: | Artificial groundwater recharge is an important engineering measure to improve the utilization level of water resources. In order to deeply research the mechanism of the infiltration, a two - dimension saturated - unsaturated seepage numerical model of infiltration pond recharging was established based on Hydrus - 2D. The mechanism of the infiltration rate decrease and＇the saturatedunsaturated change of the ＂ Moist District＂ were analyzed according to the numerical simulation. The simulation results showed that the ＂wetting front＂ moved to the saturated zone while the saturation line？ rose gradually, the recharge pool became a continuously saturated zone finally. The infiltration rate decreased to 6 785.5 em2/h rapidly afterl hour from initial 18 421em2/h, then decreased slowly, after 24 hours infiltration, the infiltration rate keep stable basically. |
