Abstract A dynamic model for the prefabricated floating slabs was presented on the basis of analysis of a floating slab track system. In the model, the floating slabs are regarded as rigid bodys supported by elastomer bearings. By exploring the effect of the layout of floating slabs on the trainbridge coupled vibration characteristics, a reasonable layout configuration of floating slabs on the floating slab track system was obtained.
