Principles of dimensional analysis have been applied to load sinkage relationships in various types of soils and snow, in order to evaluate the possibility of predicting the behavior of prototype plates on the basis of load sinkage tests performed with model footings. Encouraging results were obtained in cohesionless soils and in soils possessing little cohesion. A new dimensionally attractive load-sinkage equation has been developed whose accuracy was found to be superior to the Bekker method of load-sinkage evaluation when the work required to produce a certain amount of sinkage served as a basis of comparison. However, the Bekker method produced more accurate results if the measured and computed pressure-sinkage relationships were taken as the basis of comparison.
