NUMERICAL MODELLING OF REINFORCED UNPAVED ROADS. NUMERICAL MODELS IN GEOMECHANICS. NUMOG III. PROCEEDINGS OF THE 3RD INTERNATIONAL SYMPOSIUM HELD IN NIAGARA FALLS, CANADA, 8-11 MAY 1989
A finite element model capable of computing the behaviour of a reinforced unpaved road deforming in plane strain is described. Elastic perfectly-plastic soil models are used which are based on the use of the von mises yield function for cohesive soils and the matsuoka criterion for frictional material. The reinforcement is modelled using elastic membrane elements. The formulation is based on a large strain, large displacement eulerian approach. The finite element model is used to back-analyse laboratory scale model tests in which a footing is jacked monotonically into a model reinforced unpaved road. Some selected results of these back-analysis calculations are presented.(a) for the covering abstract of this conference see IRRD 824029.
