城市轨道交通钢轨伤损分类方法

On Classification of Rail Defects in Urban Mass Transit

为适应城市轨道交通钢轨信息化管理的需求,有必要对钢轨伤损的分类方法及相应的编号系统进行研究。根据某城市轨道交通钢轨伤损的统计结果,指出了目前城市轨道交通钢轨伤损分类方法存在的问题。通过对比国家铁路两种钢轨伤损分类方法,提出了适应城市轨道交通钢轨伤损的四位数字编号分类方法。

In order to meet the needs of information man- agement in urban rail transit, it is necessary to study the classification method and the corresponding numbering sys- tem of rail defects. In this paper, problems of rail defect classification in urban rail transit are pointed out based on the statistical result of rail defects in a city＇ s metro. By comparing two classification me^hods of rail defects in Chi- na,a method of four-digital numbering system is proposed, which will adapt to the practical condition of urban rail transit in China.
