Abstract

UIC Codes 714R & 715R recommend the use of line classifications and their usage in maintenance work by employing notional traffic loads. However, the classification has not been applied to local lines and, therefore, a new line classification system based on UIC 714R has been proposed in this study. For this, various classification models of UIC, Germany, and UK have been studied first and equivalent traffic loads based on Korail's report, as well as on train timetables, have been derived. The results of the classifications have been compared with those of major European countries and it has been shown that the proposed classification is equivalent to the average value in the European cases. The line classification can be fully utilized during the decision making process of maintenance work and will also be used to model the Reliability Centered Maintenance (RCM) in the future.

UIC Code 714R 및 715R의 규정은 열차 통과톤수에 따른 선로 등급을 산정하고 이를 기반으로 유지보수 전략 및 의사결정에 사용할 수 있는 관련 수식 및 적용방법을 제시하고 있으나, 아직까지 국내 철도노선에 대해서는 이 규정을 기반으로 한 선로등급 체계가 고려된 바 없다. 따라서, 본 연구에서는 UIC, 독일, 영국 등의 선로등급 산정기준을 조사한 후, 환산 통과톤수를 적용하는 UIC 기준에 따라 국내 주요 철도노선에 대한 선로등급을 제시하고 유럽의 선로등급과 비교 분석하였다. 이 결과, 제시한 국내 선로등급별 비율은 유럽 주요국의 선로등급별 비율과 유사한 경향을 보였으며, 통과톤수 산정이 가능한 선로 중 고속선을 포함한 1등급 621.5km, 2등급 155km, 3등급 273km, 4등급 673.8km, 5등급 571.3km, 6등급 122.3km 등으로 나타났다. 선로등급 산정 결과는 철도시설의 등급별 유지보수를 위한 기초자료로 활용될 수 있으며, 향후 신뢰성 기반 유지보수체계 적용시 대상노선을 선정하기 위한 주요변수로 활용될 예정이다.
