Summary on Grant Application Form |
|
This project will study the problem of large transient deformations of a track-bed on thin embankments located on a soft clay subgrade caused by the passage of a high-speed train travelling at a speed similar to the propagation speed of its deflection bowl (the so-called Bow-wave effect). This is analogous to the shock-wave singularity experienced by an aeroplane flying at the speed of sound. It may give rise to large transient, and consequent permanent, deformations of the permanent way which would, in turn, have a major effect on ride quality and maintenance costs. The aims of the project are to determine those situations in which the problem will, and those in which it will not, exist and to determine how minimum-intervention construction changes to the permanent way, embankment and track-bed could beneficially change the response of the system. These aims are to be achieved through a combination of soils testing, theoretical development, computational analyses and in-situ measurements, in part working alongside the designers of the new Channel Tunnel Rail Link and drawing on their existing data.
