International Journal of Structural Stability and Dynamics, 2021
For China Railway Track System (CRTS) I twin-block slab tracks, the interface between the sleeper and track slab is susceptible to damage under the coupled effect of long-term train load and external environment factors. In order to analyze the damage behavior and identify the type of debonding at the interface, this paper established a three ...

Energy harvesting from railway slab-tracks with continuous slabs
Journal of Vibration and Control, 2021This paper contributes to the literature and development of knowledge in the topic of energy harvesting by presenting the modelling and calculations of energy from vibration of railway tracks due to moving trains on floating-slab tracks with continuous slabs, considering both the quasi-static and dynamic effects.

Kaimai Tunnel track slab assessment
IABSE Congress Reports, 2021<p>Kaimai Tunnel is an 8.5km long KiwiRail tunnel on one of the busiest freight rail lines in NZ North Island. The concrete base slab that supports the track slab in the drill and blast section of the tunnel was cast on a fill layer rather than country rock.

Vehicle System Dynamics, 2009
When a vehicle runs over the connection between a floating slab track (FST) and ballasted track, wheel/rail impact may occur because of the stiffness difference in the two kinds of track, and thus a transition sector is usually included at the connection to smoothen the stiffness change.

Journal of Engineering Mechanics - ASCE, 2012
The dynamics of slab tracks and floating slab tracks are analyzed by multibeam models for the track and by integration in the wave-number domain for the soil, which is modeled as a layered half-space. Frequency-dependent compliances and force transfers are calculated for a great variety of track and soil parameters. The distribution of the load and the

Vibration characteristics of floating slab track
Journal of Sound and Vibration, 2008Abstract Coupled equilibrium equations of suspended wheels and floating slab track system were solved with the fourth-order Runge–Kutta method to obtain the deflections, vibration velocities, and wheel–rail contact forces. The program was validated through several aspects.

Design and Behavior of RPC Slab Track
Applied Mechanics and Materials, 2014Reactive Powder Concrete is proposed to be used in the ballastless track for its excellent material properties due to existing problems of high speed railway ballastless track. Three different unit types of RPC frame slab track were proposed through optimization design and the mechanical behavior of these frame slab track was analyzed. The results show
