摘　　要：本文研究当排水沟附近出现－弱透水层的地段，在入渗时和入渗停止后，沟间地下水位、流量的变化．通过分析得出两沟中点地下水位变化计算式和确定排水沟间距的计算式，可供排水地段规划设计参考使用．The water table between ditches and flow discharge variation of the drainagesystem with aquitarde during infiltration and after infiltration have been studied.The formula for calculation of water table variation and the optimum interval ofditches have been derived experimentally.
