摘　　要：该文提出了空缆实测线形分析评价的一般方法,并对其中主鞍平衡点位置的确定这一关键点提出了两种解决方法:一是基于实测鞍偏进行计算;二是基于实测空缆线形进行计算,并对这两种方法进行对比分析。并结合工程实例,对某特大悬索桥的空缆实测线形进行了分析评价。The analysis and evaluation of the measured shape of the cable at cable-finished stage was proposed in this paper.And according to the key point of the balance point of the main saddle,two methods for determinining were put forward：one was based on the measured skewing distance of the main saddle,the other was based on the measured cable shape at cable-finished stage.And both of the two methods were compared and analyzed.Combined with engineering example,the measured shape of the cable at cable-finished stage of a suspension bridge of large span was analyzed.
