摘要
高速公路道路与桥梁是公路运输体系的重要组成部分,如何保障路桥工程结构安全和行车安全是社会关注的焦点.由于路桥工程自身结构复杂、跨度大、荷载大,对施工质量要求高,再加上人为、自然等因素的影响,很容易出现一些病害问题,如桥面铺装病害、伸缩缝病害、梁体混凝土裂缝病害等.基于此,首先分析路桥工程结构病害及其成因,进而探究路桥工程加固技术的应用.
Abstract
Highway roads and bridges are important components of the highway transportation system,and how to ensure the structural safety and driving safety of road and bridge engineering is a hotspot of social concern.Due to the complex structure,large span and high load of road and bridge engineering,its high requirements for construc-tion quality,and coupled with the influenct of human factors,natural factors other factors,it is easy to have some disease problems,such as bridge deck pavement diseases,expansion joint diseases,beam concrete crack diseases,etc.Based on this,this article first analyzes the structural diseases and their causes of road and bridge engineering,and then explores the application of the reinforcement technology of road and bridge engineering.
