组合结构采用顶推法施工,分阶段形成结构刚度。该施工方法充分利用结构性能特点,具有良好的经济效益。先期钢梁顶推,梁体受力复杂,如何准确掌握顶推过程梁体的受力情况对施工过程结构的安全控制具有重要意义,本文对组合结构顶推施工的应力监控要点和应力监控策略进行了详细研究,研究成果运用于背景工程取得了良好的效果。 Combination of structures using push law construction, the formation of structural stiffness in stages. The construction method takes full advantage of structural performance characteristics, with good economic benefits. How to accurately grasp the stress condition of the beam body during the pushing process is of great significance to the safety control of the construction process structure. In this paper, the stress monitoring points and the stress monitoring strategy of the push-in construction of the composite structure Conducted a detailed study, the research results have been applied to the background project has achieved good results.
