摘要：

Floating slab track (FST) is one of the most effective countermeasures for reducing vibration induced by moving train. FST is divided into short FST (SFST) and long FST (LFST) according to the length of FST. The length of which is above 15 meters is called long floating slab track. With rail and fasteners, the structures could be treated as a Double-decked isolation system, and the formula of transmissibility of the isolation system was deduced using the receptance method. Using the receptance method, three new proposed structures parameters of FST, mass ratio, stiffness ratio and damping ratio, were deeply investigated to evaluate the effect of isolation function of the Double-decked isolation system with different structure form. And proposal values of these three ratios are given here to define the most suitable form of FST when the others values of rail and fasteners are known as actual ones.
