自锚式悬索桥施工方案的选择是通过考虑多方面的因素最终确定的,好的施工方案不仅能保证结构在整个体系转换过程中受力安全,而且能缩短工期。本文分析了自锚式悬索桥吊索常用张拉方案的优缺点,通过优化吊索张拉顺序和索鞍顶推时机,实现采用4台千斤顶并通过3轮张拉成功的实现体系转换,将吊索张拉用接长杆的数量减少到同规模桥梁的最低水平。 The choice of construction scheme of self-anchored suspension bridge is finally determined by considering many factors. A good construction plan can not only ensure the safety of the structure during the whole system conversion, but also shorten the construction period. In this paper, the advantages and disadvantages of the common tensioning scheme of self-anchored suspension bridge slings are analyzed. By optimizing the sequence of tensioning cables and the timing of jacking, a 4-jack jacking system is successfully realized through 3 rounds of tensioning, Cable tension with the number of poles reduced to the same level of the bridge the lowest level.
