摘　　要：桥梁作为人类历史上最重要的工程建设之一,自古以来就扮演着连接和沟通的重要角色。在现代社会,随着交通技术和建筑材料的不断进步,桥梁的设计和建设也越来越复杂和精细。城市桥梁主要位于城市中心或繁忙的交通枢纽,设计不仅要考虑交通流量和桥梁的承载能力,还要考虑到与城市环境的协调和和谐。而公路桥梁则主要服务于远距离的交通流动,设计注重承载能力、经济性和抗疲劳性。随着城市化的深入发展和交通需求的多样化,对于这两类桥梁的设计和管理提出了更高的要求和挑战。因此,对城市桥梁与公路桥梁的特性和设计荷载进行深入分析和比较,对于指导桥梁工程的实践和发展具有重要意义。As one of the most important engineering constructions in human history,bridges have played an important role in connecting and communicating since ancient times.In modern society,with the continuous progress of transportation technology and building materials,the design and construction of bridges have become increasingly complex and refined.Urban bridges are mainly located in urban centers or busy transportation hubs,and the design should not only consider traffic flow and bridge bearing capacity,but also coordination and harmony with the urban environment.Highway bridges mainly serve long-distance traffic flow,and the design focuses on bearing capacity,economy,and fatigue resistance.With the deepening development of urbanization and the diversification of traffic demand,higher requirements and challenges have been put forward for the design and management of these two types of bridges.Therefore,in-depth analysis and comparison of the characteristics and design loads of urban bridges and highway bridges are of great significance for guiding the practice and development of bridge engineering.
