议桥梁设计原则和桥梁加固的技术途径

Discussion on Bridge Design Principles and Technical Ways of Bridge Reinforcement

钢混叠合梁是整体连接钢梁、混凝土桥面板的新型结构,具备优良的性能。以钢混叠合梁为对象,简单介绍了钢混叠合梁的设计背景,论述了钢混叠合梁的设计原则,从钢混叠合梁的截面分析着手,探究了钢混叠合梁的设计方法,并对钢混叠合梁加固的技术途径进行了进一步讨论,希望为钢混叠合梁的设计实践与加固操作提供一些参考。

The steel-concrete composite beam is a new type of structure that integrally connects the steel beam and the concrete bridge deck, and has excellent performance. Taking the steel-concrete composite beam as the object,briefly introduces the design background of the steel-concrete composite beam, discusses the design principles of the steel-concrete composite beam, probes into the design method of the steel-concrete composite beam from the analysis of the section of the steel-concrete composite beam, and further discusses the technical approach to the reinforcement of the steel-concrete composite beam, hoping to provide some reference for the design practice and reinforcement operation of the steel-concrete composite beam.
