증속을 고려한 실대형 시험체의 동적가진시험을 통한 궤도슬래브의 거동평가

초록

Full- scale track system loading test which is effective test to simulate track-bed structure with actual wheel loading is generally similar to the field loading condition. Despite the difficulties of field conditions considering the effect of high speed running vehicle, environmental, layout, maintenance etc., the test is able to repeatedly analyze a variety of load type and to install measuring sensors without great restriction. In this study, loading condition of vehicle speed-up is simulated in lab, the behavior of rail and slab track-bed is evaluated.
