Evolution of the bearing capacity of dry loose sand with inclination of the load applied

Abstract

Vehicle wheels apply on the soil loads of variable inclination. Increasing load inclination causes a decrease in the soil bearing capacity and produces more sinkage of wheels. In the present study the change of soil bearing capacity with load inclination is investigated. Plate-sinkage tests in which load inclination to the vertical is varied from zero to thirty degrees are elaborated. A modification of Bekker's bearing capacity equation to account for load inclination is proposed, and a comparison of experimental and predicted bearing capacity curves is shown.
