Abstract

With the rapid development of the global economy and the increasing frequency of international exchanges, the number and scale of cross sea bridges, as important transportation facilities connecting different sea areas, islands, and even countries, are increasing day by day. The cross sea bridge not only provides convenience for people's travel, but also greatly promotes regional economic development and cultural exchange. This study focuses on the corrosion problem of cross sea bridge piers. Firstly, the basic concept of cross sea bridge piers and their importance in bridge structures are outlined. Subsequently, the basic theory of corrosion was elaborated in detail, including the basic principles, types and mechanisms of corrosion, as well as the key factors affecting corrosion. On this basis, an in-depth analysis was conducted on the reasons for the corrosion of the bearing platform, taking into account multiple perspectives such as environmental factors, material factors, and design and construction factors. Subsequently, a comprehensive assessment was conducted on the potential hazards of corrosion on the bearing platform, including structural performance damage, shortened bridge service life, reduced safety and reliability, and loss of economic benefits. Finally, in response to the corrosion problem of the pier cap, this study proposes corresponding prevention and control measures, including anti-corrosion materials and technology applications, structural design optimization measures, construction quality control measures, and monitoring and maintenance management strategies. Through in-depth exploration of this study, the aim is to provide theoretical basis and practical guidance for the anti-corrosion work of cross sea bridge piers, ensuring the safety, stability, and sustainable operation of the bridge.

Keywords: Cross sea bridge pier cap; Corrosion; Anti corrosion materials; Structural design
