摘　　要：结合106 m+198 m+106 m连续刚构桥,介绍了0#节段的主要施工流程和施工方法,以及悬臂挂篮施工技术,在施工中采取数字化的线性监控和严格的施工控制措施,保证连续梁施工尽量符合梁部高性能混凝土的徐变值,使后期梁部及混凝土变形尽量接近设计值。Combined with the project of 106 m+198 m+106 m continuous rigid frame bridge,this paper introduces the main construction process and construction method of 0#section,as well as the construction technology of cantilever hanging basket.In the construction,digital linear monitoring and strict construction control measures are adopted to ensure that the continuous beam construction conforms to the creep value of high-performance concrete at the beam part as much as possible.The late deformation of beam and concrete is as close to the design value as possible.

关 键 词：超大跨度 连续刚构桥 梁部施工技术 变形控制措施
