Evaluation of static and dynamic performance of floating slab track by real-scale laboratory mock-up tests

초록

The floating slab track (FST) is one of strong alternatives to attenuate the vibration of structure and ground induced by passing trains. However, the dynamic behavior of the FST is so complicated, and it should be checked in advance to application through a detailed evaluation of performance. In this study, to verify the design of recently developed FST using elastomeric bearings, the real-scale mockup test tracks have been manufactured and tested to evaluate the static and dynamic performance. Prior to the test, the numerical modal analysis has been performed to investigate the modal properties. After that, two mock-up test tracks are fabricated
