改革开放以后,随着社会经济的迅猛发展,城市化进程的加快,我国的交通运输事业也取得了突飞猛进的发展,交通建设项目在我国大地上如雨后春笋般涌现,其中公路桥梁建设是交通建设项目最为重要的组成部分,桥梁在公路建设中的占比较大,桥梁建设的安全性与其在投入使用后的耐久性,都对公路整体的使用寿命产生着重要的影响,尤其是桥梁的细部设计会直接对公路桥梁项目的结构耐久性产生至关重要的影响。本文从桥梁的分类和桥梁的发展现状谈起,对影响桥梁耐久性的主要因素进行了相应的分析与探讨,在此基础上对桥梁设计对结构耐久性的优化进行了论述,希望能够给相关的工作人员以参考启示,推动国公路桥梁建设的进一步发展。
After the reform and opening up, with the rapid social and economic development and the acceleration of urbanization, China’s transportation and transport industry has also made rapid development. Traffic construction projects have sprung up in the land of our country. Among them, highway and bridge construction is a transportation construction project The most important part is that bridges account for a large proportion of highway construction. The safety of bridge construction and its durability after being put into service have a significant impact on the overall service life of the highway. In particular, the detailed design of bridges Directly impacting the structural durability of road and bridge projects has a crucial impact. Based on the classification of bridges and the development status of bridges, this paper analyzes and discusses the main factors that affect the durability of bridges. Based on this, this paper discusses the optimization of the durability of the bridge design for structural durability, Staff reference to enlightenment, promote the country highway bridge construction further development.
