从桥梁风嘴维护中引发的思考

Thinking about Maintenance of Bridge Wind Fairing

桥梁风嘴是为了减少强风对桥面结构引起的谐振而采取的设计措施,是桥梁结构的组成部分。尤其是特大型桥梁,它是设计中不可忽视的辅助结构的重要组成部分。在现实桥梁养护工作中,由于风嘴处于空中悬臂状态,养护人员无法到达风嘴位置,给后期的桥梁风嘴维修养护工作带来一定的难度。该文从桥梁风嘴维修工作实践中,总结出了利用简易平台结构,实现了对大型桥梁风嘴的维修养护工作。同时,对类似悬臂梁结构的工程设施维修养护具有一定的指导意义。

The bridge wind fairing is the design measure taken for decreasing the resonance of the deck structure caused by the strong wind, and is a composed part of the bridge structure. It is the important composed part of the auxiliary structure not able to be neglectable in the design, especially for the oversized bridges. In the actual maintenance of bridges, the maintainers can not reach the position of wind fairing because of the wind fairing being at the overhead cantilever state, which will bring a certain difficulty to the maintenance work of the bridge wind fairing later. The article sums up the utilization of the simple platform structure to realize the maintenance work of the large- sized bridge wind fairing from the practical maintenance of bridge wind fairing. At the same time, it has a certain instructing meaning for the maintenance of engineering facilities for the similar cantilever beam structures.
