Macro-mechanical sectional modelling of ballast settlement phenomenon
Optimized management of railway networks, facing growing travelling loads and ageing of track components, requires a thorough understanding of degradation processes. Given ballast complex behaviour, its degradation is particularly critical in track maintenance management. The thesis focuses on the development and refinement of a macro-mechanical cross-sectional model that can reproduce ballast settlement under long-term cyclic
