谈大跨度预应力混凝土结构施工质量保证措施

Study of assurance measures of construction quality for long-span prestressed structure

针对大跨度预应力结构施工难度大、施工过程复杂的情况,提出了该结构施工的质量保证措施,并介绍了高支模板的施工工序及施工监测的主要内容,指出高支模架的设计与施工是影响该结构质量的重要因素,应加以重视。

According to the large-span prestressed structure with construction difficulties and complicated construction process, the paper points out the measures to ensure the construction quality, introduces the construction sequence of the high scaffolding for bracing form and the main content for the construction supervision, and points out the design and construction of the high scaffolding will affect the structural quality, so it draws attention.
