摘要:
跨海湾区域的海洋性气候明显，接触网在跨海湾长大桥梁上沿线架设，裸露在外且无备用，时刻承受强台风、强腐蚀盐雾以及大跨度桥梁伸缩、位移等恶劣环境及工程条件的考验，面临着诸多困难和挑战。本文结合我国东南沿海高速铁路的建设与运营经验，基于接触网服役特性，分别从强台风、强腐蚀及大跨度桥梁等服役环境方面，研究接触网防风、防腐蚀以及与大跨度桥梁伸缩、位移相适配的系列关键技术，并提出针对性措施及解决方案，为沿海电气化铁路的建造和运营维护提供指导。
Abstract:
In coastal regions spanning bays，the marine climate is prominent，and the overhead contact system，installed along lengthy sea-crossing bridges with no redundancy，is constantly exposed to severe conditions such as strong typhoons，intense corrosion from salt spray，and the expansion，contraction，and displacement of the long-span bridge. These challenging circumstances pose numerous difficulties and obstacles for the overhead contact system. Based on the construction and operational experience of southeast coastal high-speed railways in China，this paper，grounded in the service characteristics of the overhead contact system，investigated a series of critical technologies addressing wind resistance，corrosion prevention，and compatibility with expansion，contraction，and displacement mechanisms of long-span bridges，and examined the challenges posed by strong typhoons，severe corrosion，and the unique environments presented by long-span bridge structures. Furthermore，it proposed targeted，specific measures and solutions for these issues to guide the construction and maintenance of coastal electrified railway systems.
