依据悬索桥主缆架设时散索鞍处索股滑动的问题,考虑温度作用效应的索力差对散索鞍处索股滑动问题的影响,得出温度对索力的影响不可忽略且仅靠散索鞍静摩擦力难以因温度作用造成的边跨与锚跨索力差。
依據懸索橋主纜架設時散索鞍處索股滑動的問題,攷慮溫度作用效應的索力差對散索鞍處索股滑動問題的影響,得齣溫度對索力的影響不可忽略且僅靠散索鞍靜摩抆力難以因溫度作用造成的邊跨與錨跨索力差。

According to the sliding problem of the splay saddle＇s wire saddle strand in the erection of the main cable of the suspension bridge,the paper considers the influence of the differences of the tension of the temperature on the wire strand sliding of splay saddle,and concludes the temperature on the cable tension can be neglected and it is difficult to cause the cable tension difference between the side span and the anchor span by considering the temperature of the static friction of the loss cable saddle.
