도시철도 레일 누적통과톤수에 따른 레일마모 분석

초록

In order to predict progression of wear in the curves with operation of urban railway and, based on this, systematically manage rail wear, this study, based on data on wear measured by Seoul Metro, conducted comparison analysis on rail wear progression rate according to accumulated passing tonnage on installed rail through regression analysis by radius of curve and different rail grades, and during the progression of wear based on accumulated traffic tonnage, analyzed the progression trend of wear. As the result of the analysis, it was verified that rail wear progression based on accumulated traffic tonnage showed different trend according to radius of curve and different rail grades and after rail grinding, wear progression rate slows down for a certain period.
