한국의 고속철도 선로시스템의 연구개발 - G7 기술개발사업 중심으로

초록

The present project aims to develop applicability technologies for the stabilization and performance enhancement of newly developed track system and software. To advance the high-speed technology, the development of track engineering technology is very important. Because the development of system engineering technology for railroad structures have played a great role in the reduction of construction and maintenance costs and in the security of operation safety and riding comfort of high speed train. This article mainly discusses the R&D of the track system for high speed trains. A track is one of the most important technical elements in railway operation. Current concerns of railway development are also the main technical issues in track development. <br> The detailed research contents of a track system can be summarized as the development of an analysis technique for track design and maintenance, the evaluation of performance, and the installation of newly developed track components (rail fastener, vibration-reducing sleeper) and new type of precast slab tracks.
