Abstract

We present a numerical investigation to study the effectiveness of an elastic mattress lying under a railway to reduce traffic-induced ground vibrations. The mathematical model is two-dimensional, and the surface of the railway is assumed to be subjected to a harmonic load.

A Finite Element Method is applied to a central field including the railway and overlying a rigid foundation. The two lateral domains extending to infinity are replaced by nodal forces acting at the right and left vertical boundaries. The efficiency of the elastic foundation to reduce transmitted vibrations is expressed by the amplitude reduction factor. Several conclusions are drawn regarding the influence of various main geometrical and material parameters.
