摘　　要：通过对长期运行观测资料的分析，查明了河床辐射井长期运行出水量的衰减变化规律及其影响因素所起的相应控制作用。进而指出为获得该类型井长期运行的最佳效果，除设计时应注意从井位的正确选择与合理水位降深的选取等方面来控制淤塞进程外，还强调了在运行中要定期采取空气与高压水同时反冲洗辐射管的技术措施来恢复井的产水能力。Based on analyzing the observed data of long term operation,the attenuation law of yields and the control effect of each affecting factor are found out for dug well with infiltration pipes arranged radiantly in river bed after long term operation. Furthermore,it is worth notice,in order to slow down the attenuation of yields during long term operation,except controling the progressof siltation by properly choosing the location of well and drawdown in design,it is especially important to backwash infiltration pipes by air and high pressure water simltaneously and periodically to resume the yielding capacity of well during operation.
