โœฆ Synopsis

A PREDICTION METHOD FOR THE PROPAGATION OF GROUND

VIBRATION FROM RAILWAY TRAINS

A prediction method for ground vibration from a railway train to nearby regions involves consideration of two processes: namely, the vibration generation process and the vibration (wave) propagation process. These processes can be treated separately [1].

In this prediction method, impacts from the wheels passing over the rail joints are assumed to generate the damped free vibrations in the rail. These generated vibrations are then transmitted to the ballast, roadbed and ground. (The rails and sleepers are assumed to have the same damped free vibration.

The unsteady aerodynamic effects in railway tunnels are generally analyzed by quasi onedimensional numerical simulations which can give the effects of the pressure waves encountered in the tunnels with a low CPU cost. In the present work, a new method for predicting the evolution of the pressure in
