摘　　要：松月大坝地处严寒地区,一期工程设计为碾压混凝土重力坝,由于大坝的原设计功能不能够满足地区供水需求,因此决定对大坝进行二期加高。本文就大坝加高的结构设计中涉及的加高型式、断面设计、材料分区、新老混凝土结合面的型式等几个关键技术问题进行了探讨。Songyue dam was constructed in cold area, the type designed for dam is RCC gravity dam at stage one. The primary functions can＇t meet actual requirements of water supply, which leads to the heightening of dam at stage two. This paper discussed some key techniques during the heightening of dam, such as type of heightening, section design, material partition, type of combining face, etc.
