Description: Special Report
Abstract: In this report the deformation of snow under a vehicle is discussed. For snow with an initial density of less than 0.45 Mg/m^3, load transfer through shallow snow is shown to be attenuated by an interfacial boundary force. Evidence is presented that shows the existence of a density distribution in the deformed area. Results of a laboratory plate-sinkage test on sintered snow support this analysis. Maximum values obtained for the interfacial boundary force range from 1335 to 2670 N when the average density of the deformed area is about 0.5 Mg/m3^.
