The most common example of the application of inclined loads to the soil is the plate-grouser. This consists of a strip footing with a vertical arm at one end. The most usual loading arrangement is one in which a fixed vertical load is applied and then the horizontal load is increased until failure occurs. A theory has been developed which will predict the maximum horizontal force, assuming that the soil is dense enough to be reasonably described by the Coulomb equation. The theory is based on slip line fields including wedges of soil that are not failing. (Author)
