철도 속도등급별 전차선로 설계파라메터와 기존선 고속화 설계방안

초록

The railway speed grades from conventional rail 70km/h to high speed rail 400km/h in Total eight steps. For the catenary design, appropriate parameters should be applied for each speed and line consistency should be given. The TPS were applied mechanically to 230km/h speed up catenary design of JungAng line for PyeongChang Olympic and Honam 2nd stage section. It is necessary to present a reasonable design plan because the complexity in the construction process, difficulty in systematic management of high speed technical data, and increase of maintenance items and facilities with different speed classes are frequently repeated in the same section.
