열차의 최소안전 확보를 고려한 저비용 저도상궤도의 적용성 평가 = Evaluation of Applicability of Low Cost-Low Thickness Ballast Track System Considering Minimum Railway Safety

다국어 초록 (Multilingual Abstract)

At present, rail infrastructure in North Korea is known to be underdeveloped, far below South Koreandesign standards. The average speed of trains is 45km/h, electric power supply is unstable, normal train operation isimpossible, and large accidents such as subgrade loss due to natural disaster are concerns. In particular, there is a verybad condition of ballast track because of influx of soil. Therefore, as a first step technique of practical replacement forSouth-North Korea railway connections and to ensure minimal maintenance, it is necessary to optimize the design ofballast track according to existing railway lines. In this paper, for the purpose of improving North Korea railway, calculationsof the track structure and safety were analyzed to estimate the thickness of ballast track suitable for North Korea.
Finally, it was found to be possible to make an improvement plan for North Korea railways through calculation of ballasttrack thickness.
