摘　　要：在试验室砂槽模型中利用不同截面形状的入渗池模拟清水回灌过程,通过观测潜水水丘变化,研究了水丘位置与回灌效率的关系,比较了相同时刻瞬时入渗量与回灌总量的数据,并分析了不同截面形状入渗池的回灌效率。试验结果表明,入渗池回灌效率受截面形状影响,截面为正三角形时入渗池回灌效率最高,依次为矩形、正方形和圆形,且截面周长与入渗池的回灌效率呈正相关,实际入渗池回灌工程在开挖量一定的前提下可选取截面周长较大的形状进行回灌。The recharge process of clear-water is simulated by using infiltration pool with different section shape in sand launder model.The relationship between the position of water dome and the recharge efficiency is studied by observation the change of diving water dome.Then the recharge efficiency of infiltration pool with different section shapes is analyzed by comparing the total recharge volume with instantaneous infiltration capacity.Experiment results show that the recharge efficiency is influenced by the different section shape of infiltration pool;the infiltration pool with the equilateral triangle section shape has the highest recharge efficiency,followed by a rectangular,square and circular;the perimeter of section is positive related to the recharge efficiency of infiltration pool;it can select a section shape with the longest perimeter to be recharged when the excavation quantity is given for actual recharge project.
