Numerical analysis of railway ballast behaviour using the

The development of high speed train lines has increased significantly during the last twenty five years leading to more demanding loads in railway infrastructures Most of these infrastructures were constructed using railway ballast which is a layer of granular material placed under the sleepers whose roles are resisting to vertical and horizontal loads and facing climate action.
