摘要
根据不同跨径尤其是百米级混凝土拱桥的施工需求,开发了自适应通用拱架。介绍了该拱桥架的基本构型组成及其施工技术原理,详细论述了自适应拱架曲线型模型板的施工工艺流程,并在具体工程中进行实践应用,结果表明,自适应通用拱架有重量轻、拼装速度快等优点,具有良好的经济效益。
Adaptive universal arch frames have been developed to suit the construction needs of different spans, especially concrete arch bridges of 100 m class. The thesis introduces the basis configuration of the arch and its construction technology principles, discusses the construction process of the adaptive arch curved template, and carries out practical application in specific engineering. Results show that the adaptive universal arch is light in weight and fast in assembly speed, which has good economic benefits.
