hjic-391	Fischer, Sz.; Horvát, F.	Superstructure Stabilization of Ballast Bedded Railway Tracks with Geogrids	2011	6	.pdf	application/pdf	3930	204	46	Interlocking effect and load bearing of a reinforced ballast (modified from Konietzky, et al., 2004) Goal of the research work The research team investigates the stabilization effect of geogrid layers under railway ballast using three methods: – constructing trial field track sections where the track geometry position and its changes are regularly measured, – setting up laboratory tests which are adequate for determining parameters related to ballast material- geogrid interaction, – computer-aided modelling for improving and generalizing the relationships. The changing of interlocking effect in the ballast material as a function of vertical distance from geogrid layer is a key-role for the conformability of evaluation of geogrid 103 reinforcement’s use.	cache/hjic-391.pdf	txt/hjic-391.txt
