레일 신축이음매의 종방향 거동에 대한 RLR 체결구의 영향

초록

The end zone of the rail expansion joint in the continuous welded rail track are typical vulnerable place due to the longitudinal movement of sleepers. This study investigated the controlling method of the longitudinal movement of sleepers without change of the characteristic of the expansion behavior such as the amount of rail expansion, the length of the breathing zone, etc. Especially, this paper presented effect of the RLR(Reduced Longitudinal Restraint) fastener that reduce the longitudinal resistance of fastener.
