摘　　要：新版铁路桥梁图和桥梁支座通图明确了桥梁各类钢构件的防腐涂装标准及要求。通过对比分析现行的铁路造价标准与现行的桥梁相关防腐涂装标准之间的匹配性,本文详细分析梳理了桥梁涂装方面现行标准中需要完善的补充单价条目,并提出了对应的解决方案,为进一步合理确定铁路工程投资,同时为现行造价标准的完善提供一定的支撑。另外,结合桥梁附属钢结构经常采用的复合防腐层的补充单价分析过程,介绍补充单价分析的思路和方式,以供其他项目参考。The new version of railway bridge drawings and bridge bearing diagrams clarify the anti-corrosion coating standards and requirements for various steel components of bridges.By comparing and analyzing the compatibility between the current railway cost standards and the current bridge related anticorrosion coating standards,this article provides a detailed analysis and sorting of the supplementary unit price items that need to be improved in the current standards for bridge coating,and proposes corresponding solutions to further rationally determine railway engineering investment and provide certain support for the improvement of the current cost standards.In addition,based on the analysis process and results of the supplementary unit price of the composite anti-corrosion coating commonly used in bridge ancillary steel structures,this article introduces the ideas and methods of supplementary unit price analysis for reference by other projects.
