摘　　要：针对独塔自锚式吊桥施工工艺复杂性及设计优化的需求,研究依托某大桥工程,分析了独塔自锚式吊桥的基本构造,针对施工方法展开优化设计。通过对独塔自锚式吊桥进行施工监测,验证了研究提出的优化方案的有效性。结果表明:标高误差最大仅0.012 m,吊索位置上游与下游的误差平均值分别为2.57 mm与3.34 mm,索力值误差均在±3.00%以内。In view of the construction process complexity and design optimization requirements of single-tower self-anchoring suspension bridge(STSSB),the basic structure of STSSB is analyzed based on a bridge project,and the optimization design is carried out according to the construction stage and construction method.The validity of the proposed optimization scheme is verified by the method of monitoring the construction of the STSSB.The results show that the maximum elevation error is only 0.012 m,the average error of upstream and downstream sling position is 2.57 mm and 3.34 mm,respectively,and the error of cable force value is within±3.00%.
