摘要
本文研究了构件尺寸偏差对苏通大桥施工控制的影响,分析了塔的高度、施工完成时塔的垂直度、钢箱梁的无应力线形和无应力长度、斜拉索的无应力长度等因素的尺寸偏差对主梁线形的影响,为苏通大桥施工精度控制标准的制定提供了理论依据。苏通大桥的高质量建成通车,验证了本文分析结论的可靠性。
The influence of constructional elements＇ size deviations on the construction control of Sutong Bridge is investigated. The effects of some size deviations on the bridge alignment, such as tower height, tower sag, stress-free alignment and length of steel box girder, and stress-free length of cable are analyzed, in order to provide a theoretical basis for the development of Su-Tong Bridge Construction＇s precision control standards. The high-quality completion of Su-Tong Bridge confirms the reliability of the conclusions shown in this paper.
