摘　　要：在北方大部分地区有较长的寒冷季节,受工期和各种因素的影响,桥梁承台墩身冬季施工几乎是不可避免的,冬季施工混凝土质量直接影响着桥梁结构的使用功能,冬季施工混凝土质量控制历来是施工质量控制的重点及各建设参与方的关注点,其中,混凝土浇筑及养护过程中的温度控制又是质量控制的控制要点之一,因此,论文针对北方地区(寒冷地区)冬季墩台混凝土现场浇筑及养护过程中的温度控制措施及控制要点进行了分析,以期为以后相关施工提供借鉴。There is a long cold season in most areas of north China. Due to the influence of construction period and various factors, winter construction of bridge bearing platform and pier body is almost inevitable. The quality of concrete construction in winter directly affects the function of bridge structure. The quality control of concrete construction in winter has always been the focus of construction quality control and the concern of all construction participants. Among them, the temperature control in the process of concrete pouring and curing is one of the key points of quality control. Therefore, the paper analyzes the temperature control measures and control points in the process of concrete pouring and curing in the northern region(cold region) in winter, in order to provide reference for the future construction.
