摘　　要：越南昆江2一级水电站大坝属大体积混凝土结构,坝体混凝土采用通仓浇筑,因此控制混凝土基础、内外与上下层温差,使大体积混凝土内外形成比较均匀的温度场,是防止坝体混凝土温度裂缝的关键。通过分析坝区的气象条件和混凝土的热学力学性能,提出了合理的坝体温度控制措施,实践证明温度控制措施是可行的。The main dam of Vietnam Kunjiang 2-1 Hydropower Station is a large concrete structure. Concreting without longitudinal joint is adopted for dam body, so it is very important to control the temperature difference of foundation, internal and external parts, upper and lower layers, so as to prevent concrete temperature cracks with relatively uniform temperature field. Based on analysis of the meteorological conditions of dam area and thermal mechanical properties of concrete, proper temperature control measures were put forward and had been proved feasible by practice.
