摘要
混凝土大体积水化热一直是坝工界研究的重难点问题,混凝土温度应力、温控措施在大坝设计施工中是非常重要的。文章结合实际工程,基于设计规范和基础温差条件,计算分析混凝土施工期不同月份的温度应力,研究总结高低温季节的入仓浇筑、保温及散热措施,所得成果对于混凝土重力坝的设计施工具有一定的参考价值。
Mass hydration heat of concrete has always been a difficult and important problem in dam engineering field.Concrete temperature stress and temperature control measures are very important in dam design and construction.Combined with the actual project,this paper calculated and analyzed the temperature stress of concrete construction period in different months according to the design code and basic temperature difference conditions to research and summary the casting,heat preservation,and heat dissipation measures the high and low temperature seasons,and the results have a certain reference value for the design and construction of concrete gravity dam.
