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.

Debonding Analysis and Identification of the Interface Between Sleeper and Track Slab for Twin-Block Slab Tracks

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 ...

Slab Track Mass-Spring System

Transportation Research Record: Journal of the Transportation Research Board, 2012
Development of a ballastless slab track structure with a mass-spring system began about 20 years ago, and different kinds of these track systems have been successfully in use for urban transportation systems. With these systems the elastic elements are inserted under the slabs to provide protection from bothersome vibration and noise.

Vibration characteristics of floating slab track

Journal of Sound and Vibration, 2008
Abstract 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.
