随着时代的进步和社会经济的发展,我国交通运输事业发展迅速,其中桥梁是交通体系中非常重要的一个组成部分;我国很早就有浮桥出现,且得到了广泛运用。但是,在如今的桥梁结构设计中,因为种种缺陷,往往会给以后的桥梁使用带来安全隐患,影响到人们的生命财产安全,需要引起足够的重视。本文简要分析了现代桥梁结构设计中钢结构的完整性设计,希望可以提供一些有价值的参考意见。 With the progress of the times and the development of society and economy, the transportation and transport in our country have been developing rapidly. Among them, the bridge is a very important part of the transportation system. The pontoon bridge appeared very early in our country and has been widely used. However, in today’s bridge structure design, because of various defects, it often brings security risks to future bridge use and affects people’s life and property safety, which needs sufficient attention. This article briefly analyzes the integrity design of steel structure in the design of modern bridge structure, hoping to provide some valuable reference suggestions.
