摘　　要：结合某钢箱系杆拱桥的施工,基于寒冷气候条件下焊接技术条件要求,通过研究焊剂质量通病、钢箱系杆拱不同部位结构型式,提出了钢箱系杆拱桥在寒冷气候条件下的焊接施工控制措施,有效保证了冬季焊接施工质量和工程施工进度,提高了工作效率,可供同类桥梁的焊接施工借鉴。Combined with the construction of a steel box tied arch bridge and based on the requirements of welding technical conditions under cold climate conditions,the welding construction control measures of the steel box tied arch bridge under cold weather conditions are proposed,by studying the common problems of flux quality and the structural types of different parts of steel box tied arch bridge.These measures effectively guarantee the welding construction quality and the construction progress,have improved the work efficiency,and can be used as a reference for the welding construction of similar bridges.
