Study on durability assessment and maintenance strategy of highway bridges
高速公路桥梁耐久性评估与维护策略研究

摘要

在高速公路网络蓬勃发展之际，桥梁作为关键节点，其耐久性问题备受瞩目。本研究聚焦于此，全面考量环境侵蚀、车辆荷载、材料老化等多方面因素，运用先进检测技术收集数据，借由科学模型量化评估。进而制定涵盖日常养护、病害修复、加固改造的维护策略，致力于增强桥梁耐久性，延长服役期限，保障交通流畅，降低运维成本，为桥梁管养提供有力支撑。

Abstract

Amid the thriving development of highway networks, the durability of bridges as critical nodes has garnered significant attention. This study focuses on this issue, comprehensively considering multiple factors such as environmental erosion, vehicle loads, and material aging. Advanced testing technologies are employed to collect data, and scientific models are used for quantitative assessment. Consequently, maintenance strategies that cover daily care, disease repair, and reinforcement are formulated. The aim is to enhance bridge durability, extend service life, ensure smooth traffic flow, reduce operation and maintenance costs, and provide strong support for bridge management.
