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.
越南昆江2一級水電站大壩屬大體積混凝土結構,壩體混凝土採用通倉澆築,因此控製混凝土基礎、內外與上下層溫差,使大體積混凝土內外形成比較均勻的溫度場,是防止壩體混凝土溫度裂縫的關鍵.通過分析壩區的氣象條件和混凝土的熱學力學性能,提齣瞭閤理的壩體溫度控製措施,實踐證明溫度控製措施是可行的.

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 rela?tively 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.
