Meyerhof’s approaches: The important difference between Terzaghi’s and Meyerhof’s approaches is that the latter considers the shearing resistance of the soil above the base of the foundation, while the former ignores it. Thus, Meyerhof allows the failure zones to extend up to the ground surface (Meyerhof, 1951) Skempton proposed equations for bearing capacity of footings founded in purely cohesive soils based on extensive investigations (Skempton, 1951). He found that the factor Nc is a function of the depth of foundation and also of its shape. Brinch Hansen (1961) has proposed the following semi-empirical equation for the bearing capacity of a footing, as a generalization of the Terzaghi equation. It has been found that Hansen’s theory gives a better correlation for cohesive soils than the Terzaghi theory, although it may not give good results for cohesionless soils.
