摘要
结合首都机场滑行道底板施工,分析了超长大体积钢筋混凝土结构裂缝产生原因,介绍采用补偿收缩混凝土和设置膨胀加强带的措施来保证施工质量,并介绍了相关施工注意事项。
With the bottom slab project of the taxi track of the Capital Airport as a practical example, the paper analyzes the causes that lead to the cracking of super-long, large-sized reinforced concrete structures, with stress placed on the improving measures such as the make-up contracting concrete, the provision of the reinforced expansion bands, etc. to ensure construction quality. It also outlines some corresponding points worth our attention during construction.
