摘　　要：针对雨洪资源地下回灌工程易堵塞、效率低、寿命短等问题,以入渗池为例,开展室内模拟实验。实验通过模拟雨洪资源地下回灌条件和过程、设定渗透介质的表面形态和回灌的工程工艺方法,观测渗透速率随时间的变化规律,分析堵塞层悬浮物的分布规律;通过对比相同目标补给层、不同回灌工程工艺方法对入渗速率的影响,分析促渗机理,评价堵塞的形成机制和管理方法,探索促渗关键技术。提出了局部高位入渗方法、垄沟池底方法、间歇回灌方法三种有效的促渗技术,对雨洪资源地下回灌的工程实践具有一定的借鉴意义。Rain flood water harvasting through underground storage space has been more and more recognized by the society.However,its practice is seriously limated by the special charactereristcs of rain flood water,anquifer clogging,instruments＇ efficiency,longevity,as well as maintenance costs.This study takes an infiltration basin as an example,and examines the key techniques of infiltration promotion through indoors simulation experiments.In the experiments,infiltration conditions process are particularly set to observe the dynamic variation of infiltration rate and to seek the clogging location regulation.The core of the experiments is to simulate different engineering techniques and processes in each certain recharged aquifer and conditions,and through contrast,promotion mechanisms of different settings are discovered.Based on the mechanisms analysis,this paper puts forwards three kinds of promotion methods,such as Local High-level Infiltration Method,RV（ridge vale） Bottom Method,and Alternate Method.
