A CONSISTENT MODEL FOR SOIL STRUCTURE INTERFACE BEHAVIOUR. NUMERICAL MODELS IN GEOMECHANICS. NUMOG III. PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM HELD AT NIAGARA FALLS, CANADA, 8-11 MAY 1989

This article describes a consistent model of soil-structure interface behaviour. The model uses an interpolation in order to predict the incremental response along a given direct shear path. These basic paths are obtained from direct shear tests between a sand and a rough metallic plate. The only paths readily obtained in the laboratory are: (a) direct shear at constant normal stress; (b) direct shear tests at constant volume; and (c) pseudo-oedometer tests (oedometer tests on an already sheared sample). Both the loading and unloading phase for each test is considered which gives 6 identification paths. The tests are performed on a specially modified shear box. The limitations of the model are discussed from two viewpoints: (a) those caused by limitations due to the shear box equipment; and (b) those due to the model itself. For the covering abstract of the conference see IRRD 824029.
