Abstract

In case of damaged timber sleepers, maintenance is carried out according to the track inspection standard. However, it is difficult to detect the extent of damage on the bridge, and maintenance is depended on inspector's judgment. In this study, we propose to improve the evaluation criterion of timber sleepers for the ballast-less tracks on serviced urban railway bridge. The timber sleepers on railway bridge was classified according to degree of damage, and damage scores were calculated for each damage grade. Also we have improved the maintenance system of the timber sleepers through the history management system of the individual timber sleepers on railway bridge. As a results, it was judged that systematic management of timber sleepers could be possible during maintenance.

본 연구에서는 무도상 궤도가 부설된 국내 도시철도의 철도 교량상 목침목에 대한 선로검사내규의 점검사항 및 불량판정 기준을 개선하여 목침목의 손상유형에 따른 상태등급체계를 분류하고 침목별 이력관리대장 시스템 도입을 통해 목침목의 유지관리체계를 개선하고자 하였다. 이를 위해 본 연구의 대상 철도교량에 부설되어 있는 목침목의 손상현황을 분석하여 손상별 코드를 구축하였으며, 침목별 손상 및 유지관리이력을 관리할 수 있는 유지관리시스템 도입을 통해 단면형상 및 침목 고정장치가 다양하고 유지관리가 복잡한 무도상 철도교량상 목침목의 체계적인 유지관리가 가능할 것으로 판단되었다.
