摘要
文章以甘肃省定西市某高速项目钢盖梁框架墩设计为例,研究钢盖梁框架墩在高速公路中的灵活应用,提出了钢盖梁框架墩的结构形式,并解决了钢盖梁刚度与桥梁结构的变形控制、钢盖梁与混凝土桥墩的可靠连接等关键技术问题。
Taking the design of the steel-capped beam frame pier of a high-speed project in Dingxi City, Gansu Province as an example, this paper studies the flexible application of the steel-capped beam frame pier in expressways, puts forward the structural form of steel-capped beam frame piers,and solves the key technical problems such as the stiffness of the steel-capped beam, the deformation control of the bridge structure, and the reliable connection between the steel-capped beam and the concrete pier.
