摘　　要：为系统分析高寒地区吊杆索力受温度影响及修正问题,选取三跨系杆拱桥中5根吊杆进行索力测试。基于现场实测数据,采用相关性理论确定温度与索力间的关系,建立“吊杆频率-大气温度-有效索长”的回归模型,对吊杆索力中温度的影响进行修正,得出了一些有益的结论。In order to analyze the influence of temperature on suspender cable force and its correction systematically in alpine area,five suspenders in three span tied arch bridge are selected for cable force test.The relationship between temperature and cable force is determined by correlation theory and the regression model of“suspender frequency atmospheric temperature effective cable length”is established based on field measured data,the influence of temperature on suspender cable force is corrected,some useful conclusions are drawn.
