도시철도 레일 열화손상의 상관관계 연구 및 분석

초록

Currently 97% of urban rail track Concrete (STEDEF) Subway Line Extension Period in orbit 348km (339km) consists of a concrete bed. Specific parameters that affect the rail deterioration damaged defective rail exchange management rail deterioration damaged review analyzed data from the on board range from the subway opening time until the first half of 2016 in view of the orbital characteristics of the concrete roadbed variable than the gravel track factors, the normal force , hoengapryeok , axial force , the accumulated tonnage passing by , affiliated elapsed analyzed the correlation period . It is thought to be able to be utilized in the improvement of future efficient rail defect management.
