英文摘要：

In view of the problems in rising seepage line which endangers the safety of dam,the key construction technology of radiation well was discussed in the paper.Based on the project practice,the composition and the sinking principle of radiation wells are introduced,mainly introducing the key construction technology of the main well,the radiation filter tube and the aqueduct.Some countermeasures are put forward to deal with some special situations in the process of construction.The construction effect is remarkable which has a strong reference value to similar projects.
