Abstract:

The recent growth in the use of the railway and particularly that of in urban areas highlights the need to investigate the technical aspect of slab track. This paper discusses dynamic behaviour of slab track. The vertical stiffness of track bed is assumed to be random variable. By employing the Monte Carlo method, the response of track is obtained. The track simulation is performed by double beam theory. The model consists of an upper Euler–Bernoulli beam to account for the rail and a lower Euler–Bernoulli beam to account for the slab. There are two continuous resilient layers in the model: one to account for rail pads between the rails and slab and one to account for track bed underneath the slab. Finite element method is used for analyzing the track behaviour and the effects of various parameters are investigated.
