Abstract

The tamping operation is employed to restore the geometry of railway track distorted by train traffics. In order to study the micro mechanical properties of railway ballast under tamping operation, the analysis model of railway ballast under tamping operation is created using the discrete element method, numerical simulations are performed to study the evolution of contact force inside railway ballast under tamping operation. The obtained results are showed that the contact force inside railway ballast is enhanced by tamping operation, so as to improve the carrying capacity and stability of railway track.
