桥型象限图在构建协作体系桥梁中的研究

为推动协作体系桥梁的发展，本研究利用桥型象限图对多座现有协作体系实桥进行了构建验证，并通过桥型象限图构建出多种新的不同结构类型的协作体系桥梁。研究表明协作体系桥梁是以五类基本桥型为基础的复杂桥梁，基于桥型象限图能排列、组合出各种不同结构类型的协作体系桥梁。根据协作体系桥梁的特点，提出一类针对大跨度梁式桥跨中下挠病害的加固专用协作体系桥型方案。桥型象限图可为今后协作体系桥梁的设计与研究，提供一种简单快捷方法。

Research on the Bridge Type Quadrant Diagram in Build-ing Collaborative System Bridge Diagrams

To promote the development of collaborative system bridges, a bridge type quadrant diagram is utilized in this study to build and validate multiple existing collaborative system bridges. Through the bridge type quadrant diagram, various new types of collaborative system bridges with different structures are built. The research indicates that collaborative system bridges are complex structures based on five basic bridge types. Using the bridge type quadrant diagram, various structural types of collaborative system bridges can be arranged and combined. Considering the characteristics of collaborative system bridges, a specific collaborative system bridge scheme is proposed to address mid-span deflection issues in large-span beam bridges. The bridge type quadrant diagram can be used to develop a simple and efficient method for the design and research of collaborative system bridges in the future.
