자기부상열차 가이드웨이 거더의 실험적 연구 : PSC-U 형 거더와 프리캐스트 바닥판의 합성 시스템

초록

Maglev is a system that a train rus levitated above a rail. Therefore it is very important to maintain a constant leviation gap for achieving serviceability and ride comfort. This study is a cooperation research subject of the 3-1 subject. perfoemance improvement of maglev track structures, of the Center ofr Urban Maglev Program in Korea, started in 2006. the aim of this study is development of rapid constrcutions of bridge superstructure for maglev. At present, precast deck is widely used because of its superiority to cast-in-place concrete on quality and the term of works. The research group suggested basic systems of maglev guideway with PSC-U type and trapezoidal open steel box type girder, and precast deck. cooperating with Korea Railroad Research Institute, the managing institute of the 3-1subject. In this study, longitudinally full-scale guideway girder system was fabricated and static/dynamic test of the firder was performed for the purpose of the performance evaluation
