연속 프리캐스트 콘크리트 슬래브궤도에서의 온도하강에 따른 슬래브 이음매 개구량 해석

다국어 초록 (Multilingual Abstract)

Precast concrete slab track is a track structure to be installed by transporting and assembling precast concrete slabs manufactured at the factory. This method can improve concrete quality provide easy maintenance and reduce construction time compared with in-situ concrete track. However the concrete slabs being continuously connected in longitudinal direction due to the temperature change between summer and winter the openings at slab joints have occurred. Thus in this study to identify the cause of this opening of slab joint the joint opening caused by temperature drop in the longitudinally continuous precast concrete slab track has been predicted using three-dimensional finite element analysis and compared with field measurements. Based on the proven model the slab joint opening and the stress pattern of concrete slab and steel reinforcement according to concrete slab-base friction properties concrete-reinforcement bond properties and prestressing were analyzed.
