IN-PLACE DETERMINATION OF TOPSOIL SHEAR PROPERTIES FOR OFF-ROAD VEHICLE TRAFFIC

Résumé

The study of the off-road mobility for a vehicle consists in the study of its drawbar pull on a given sol and can be calculated by models such the Janosi-Hanamoto's model which depend on the soils mechanic parameters like the angle of friction and the cohesion. These parameters result generally from shear tests. The annular shear test is often used to estimate the soil shearing for mobility studies. Other shear test is the translation shear test which consists in the translation at a constant speed of a loaded plate with a smooth interface or with grousers. This article aims to present the validation of the translation shear test for the study of the shearing of the granular surface soils and the methodology to apply to link this operational test to the efforts measured during full-scale tests. An experimental device was developed to perform superficial translation shear tests of a loaded plate at slow speed or fast speed to obtain the shearing forces.
