大吨位超高支架设计与施工是桥梁建设中的难题,本文以湖南某大桥主桥混凝土索塔支架为例,介绍了大吨位超高支架的设计方法、材料选择、荷载计算、支架变形影响因素及控制措施,大桥至今没有发现任何质量问题,工程质量优良,该工程成功的案例可以为今后类似大吨位超高支架体系提供技术参考。 The design and construction of large-tonnage superhigh-stents is a difficult problem in bridge construction. In this paper, taking a concrete tower pylon of a main bridge in Hunan as an example, the design method, material selection, load calculation, influential factors And control measures, the bridge has so far found no quality problems and the quality of the project is excellent. The successful case of the project can provide technical reference for the future similar large-tonnage super-tall stent system.
