3结语
钢立柱是声屏障屏体的主要结构支撑件,其使
用寿命的长短决定了声屏障工程总的使用期限,而
钢立柱表面防腐技术又直接决定了其使用寿命,因
此,在声屏障工程中,对于钢立柱防腐涂装体系选用
应引起足够重视,应根据实际大气环境条件,选择经
济、合理的防腐涂装体系。
此外,要保证防腐涂装体系的经济长效,不仅需
要合理、科学的设计,还应关注防腐施工质量。

Abstract:The sound barrier is one of the main mitigation measures for traffic noise of expressway.The selection of anticorrosive coating system for the steel column of sound barrier directly determines the service life of the sound barrier,and the anticorrosive coating system is directly related to the atmospheric environment corrosion level within the scope of expressway road.The influence of vehicle exhaust should be considered when determining the corrosion level of atmospheric environment in the highway area.Based on the analysis of the impact of vehicle exhaust on the atmospheric environment of the road area,the current technical specifications and anti-corrosion specifications of the sound barrier,combined with the environmental air quality of Shanxi Province,the recommended coating system for the steel column of the sound barrier of the highway in Shanxi Province is given,which provides a reference for the design of the sound barrier project.
Key words:expressway;sound screen barrier steel column;anticorrosive coating system
