This report presents the results of a study performed on the behavior, particularly the deformation, of snow under a load applied to a rigid plate at a constant rate of penetration. The results will eventually be used in the development of design criteria for snow roads, runways, and foundations in the polar regions. The tests were conducted on snow samples having a high width/length ratio, simulating a two-dimensional case. The effect of snow density, plate size, and pressure on the deformation of snow below the load was investigated. The pressure-sinkage relationships and the bearing strength as functions of density were also investigated. (Author)
