摘　　要：为了增加地下水开采水量,并且尽可能地减小地下水开采后的水位降深,在水源地下游设置地下截水坝,并且同时配合辐射井开采地下水。通过数值模型的计算及预测,截潜流工程不但可以有效地截取地下水径流,更大限度地利用地下水资源,而且可以有效地控制地下水位降深以及腾出地下库容,以便在洪水期容纳更多的洪水入渗。通过实际工程的检验表明:地下截水坝配合辐射井这种截潜流工程在地下水开采中具有重要的作用。In order to increase the exploitation of groundwater and reduce the water level drawdown after groundwater exploitation as much as possible, an underground dam and radiation wells are built to cut-off runoff and exploit groundwater simultaneously. Through the numerical modeling of calculation and prediction, intercepting underflow project not only intercept effectively the groundwater runoff, but also control the water level drawdown, increasing the underground storage capacity in order to accommodate more infiltration of flood. The results show that underground dam with radiation well as the intercepting underflow project play an important role in groundwater exploitation.
