摘　　要：拱坝一般比较单薄,温度应力对拱坝安全的影响非常显著,在严寒地区温度应力会更加突出。以新疆某高拱坝的拱冠坝段为例,旨在遴选不同月份施工时大坝混凝土的温控措施及温度控制指标,达到大坝混凝土施工期防裂的目的。Arch dams are generally thin,and the temperature stress has a significant influence on dam safety.The temperature stress in cold area would be more prominent.Taking the arch dam section of a high arch dam in Xinjiang as an example,the purpose of this paper is to select the temperature control measures and temperature control indexes of dam concrete during construction in different months,so as to achieve the goal of cracking prevention.
