摘　　要：基于国内外悬索桥主缆缠丝设计,从缠丝力变化的各个阶段入手,分析缠丝力变化的原因,提出主缆缠丝力新的计算方式。根据某座主跨450 m悬索桥的主缆缠丝力分析,对各种计算理论的结果进行比较、分析,供参考。Based on domestic & internationa main cable wrapping wire design, starting from various stages of wrapping wire force variation,analyzing the reasons wrapping wire force changes,a new method for calculating the wrapping wire force of the main cable is presented. According to the analysis of the main cable wrapping wire force of a main span 450 m cable suspension bridge,the results of the calculation of the various theories are compared & analyzed, which can provide references for similar projects.
