摘　　要：“十四五”期间,交通运输部集中开展危旧桥梁改造专项行动,针对国省干线公路老旧弱危桥梁进行改造,保证了人民安全出行,并对完善公路路网、提升桥梁功能起到重要作用。以S208太白大桥为例,全面介绍干线公路桥梁承载能力评定、桥梁改造目标和设计方案,对改造后重点受力部位进行实体建模和结构受力分析,结果表明桥梁承载能力满足现行规范要求,改造后桥梁满足非机动车行驶及管线过桥需求,节省了工程造价,为同类型桥梁改造提供了设计思路。During the 14th Five Year Plan period,the Ministry of Transport launched a special campaign to renovate old and weak bridges on national and provincial trunk highways,ensuring the safety of people's travel and playing an important role in improving the highway network and enhancing bridge functions.Taking the S208 Taibai Bridge as an example,this article comprehensively introduces the evaluation of the bearing capacity of mainline highway bridges,the goals and design schemes of bridge renovation,and conducts solid modeling and structural stress analysis on the key load-bearing parts after renovation.The results show that the bearing capacity of the bridge meets the current regulatory requirements,and the renovated bridge meets the needs of non-motorized vehicle driving and pipeline crossing,saving engineering costs and providing design ideas and references for the renovation of similar bridges.
