Abstract: In this paper, based on the elastic foundation beam theory, the influence rules of every combination of loads and operating modes for ballastless track of Linear Induction Motor (LIM) track traffic are studied. In addition, according to the construction character of prefabrication and cast-in-situ, the rules of how construction influences the mechanical characteristics of the ballastless track structure are given. On the basis of synthetical analysis of the distribution rules of ballastless track’s internal force, some appropriate suggestions for design and construction are put forward.

Abstract: In this paper, in order to do research on the characteristics of reducing vibration and declining noise of concrete floating slab track, the vertical dynamic analysis model of vehiclefloating slab track is established with the use of finite element analyses method. By using this model, dynamic responses of floating slab track are studied under different conditions of train’s speed, stiffness and damping of infrastructure, structure size, etc. On the basis of this research, some suggestions for design of floating slab track are put forward.
