摘　　要：公路桥梁工程作为关键的基础设施,对区域连通和发展具有重要作用。桥梁结构种类繁多,大跨度桥梁在其中占据重要地位。为了提升大跨度桥梁的建设质量,需要深入研究其结构设计方案。文章主要探讨大跨度公路桥梁的设计原理,详细阐述大跨度斜拉桥、悬索桥和拱桥的结构特性、设计要点和优化设计策略,并结合大跨刚构桥实际工程案例,全面探讨大跨度桥梁结构设计方案。As a key infrastructure,highway bridge engineering plays an important role in regional connectivity and development.There are many kinds of bridge structures,and large-span bridges occupy an important position in them.In order to improve the construction quality of large-span bridges,it is necessary to study its structural design scheme in depth.This paper mainly discusses the design principle of large-span highway bridges,expounds the structural characteristics,design points and optimization design strategies of large-span cable-stayed bridges,suspension bridges and arch bridges in detail,and comprehensively discusses the structural design scheme of large-span bridges in combination with the actual engineering cases of large-span rigid frame bridges.
