摘要
夷陵长江大桥是一座采用平行钢绞线体系斜拉索的三塔混凝土单索面斜拉桥。由于桥梁采用了新结构、新工艺、新材料,因此在主梁架设中也碰到了很多新问题。主要对施工监控中斜拉索张拉次数、斜拉索自重对索力的影响、斜拉索索力测量问题进行详细的分析。
Yiling Changjiang River Bridge is a 3pylon concrete cablestayed bridge with PPWS cable system and single plane stay cables. Quite a few new problems were encountered in the erection of the main girder of the Bridge owing to utilization of the new structures, workmanships and materials on the Bridge. In this paper, the times of cable tensioning, the influence of dead weight of stay cables upon cable force, and measurement of cable force in the construction monitoring and control are analyzed in considerable details.
