摘　　要：果多水电站是扎曲西藏段水电规划“两库五级”中的第二个梯级电站,位于西藏自治区昌都市境内,距昌都市公路里程59 km,是西藏地区目前已建成的第一座碾压混凝土重力坝。为确保碾压混凝土施工质量,在果多水电站设计及施工过程中通过研究西藏高原寒冷气候对碾压混凝土浇筑的不利影响、施工控制难点以及低温季节碾压混凝土施工温控方案等,提出了西藏地区高海拔条件下碾压混凝土施工控制措施和诸多特点,该成果可为后续类似工程提供参考。Guoduo Hydropower Station is the second cascade hydropower station in the"two reservoirs and five levels"hydropower planning of Tibet section of Zhaqu.It is located in Changdu city of Tibet Autonomous Region and 59 km away from Changdu city highway.It is the first RCC gravity dam that has been built in Tibet.In order to ensure the quality of RCC construction,in the design and construction process of Guoduo Hydropower Station,through the study of the adverse effects of cold climate on RCC pouring in Tibet Plateau,the difficulties of construction control and the temperature control scheme of RCC construction in low temperature season,etc.,this paper puts forward the RCC construction control measures and many characteristics under high altitude conditions in Tibet region,which can provide reference for follow-up similar projects.
