OVERVIEW OF URBAN MAGLEV STRUCTURES IN KOREA

초록

In this study, an overview of urban Maglev structures in Korea and an ongoing performance verification test criteria about guideways and tracks are introduced. Urban Maglev pilot line in Korea is ahead of the opening in november and preliminary vehicle test and commissioning is carrying out. The length of the line is about 6.1km from Incheon international airport to Yongyu and has 6 stations. Displacements, accelerations and strains of the guideways and tracks are measured and examined whether it meets the performance requirements in structures verification test and track alignment inspection as well. Keywords : Maglev, Guideway, Performance verification criteria, Displacement, Track Irregularity. 1. INTRODUCTION The practical application R&D project which the train runs floating above the track to enhance speed and reduce noise without wheels, has been started by the Ministry of Land, Infrastructure and Transportation since the beginning of 2007 in Korea. Urban Maglev pilot line started construction in 2011 and construction was completed in June 2013. Total length of the route is approximately 6.1km and there are 6 stations including the Incheon International airport station. Maglev structures were constructed in the form of a viaduct type and consists a special form of the track (guideways, sleepers, turnouts, etc.) different from general railroad structures because of characteristics of Maglev, noncontact between track and bogies.
