The pressure-sinkage relation of dry loose sand is one of the main problems considered for a vehicle to drive in desert. It is affected by loading patterns. Based on plate-sinkage tests, the effects of two different loading patterns on the pressure-sinkage relation of dry loose sand are studied. One is that the plate is horizontal with the angle of load relative to the plate normal varying from 0 to 30 deg of angle. The other is that the load is perpendicular to the plate with the angle of the plate relative to sand surface varying from 0 to 30 deg of angle. The results indicate that the pressure-sinkage relation of dry loose sand in both the above mentioned cases are different from that in the horizontal plate-vertical load case and that if the sinkage-pressure under the horizontal plate-inclined load case is used to determine the normal stress distribution under the tire, a precise prediction of tractive properties of a wheel can be obtained.
