Abstract

Experimental and numerical discrete element analyses have been performed to investigate trackbed behaviour for concrete mono-block and steel sleepers. For the laboratory and numerical approaches considered, ballast settlement as well as ballast-subgrade interface pressure is measured. Consideration is also given to the steel sleeper installation process by the comparison of a statically driven steel sleeper to a "wished-in-place" configuration.
