The strength of soil is a key parameter in designing foundations and other earth structures. In shallow foundation design, the capacity of the foundation to support footing load is dependent on the soil’s bearing capacity which is a function of its strength parameters. According to [4], bearing capacity is the maximum pressure that the soil can support at foundation level without failure. Proper interpretation of specific shear strength parameters of clay and the application of this case to bearing capacity problems was presented and reviewed in this paper. The influence of the shear strength parameters of subsoil on its bearing capacity are very important, especially, when changing the angle of internal friction. The results of calculations for low plastic clay subsoil, shown in the work, illustrate exemplary how a level of its bearing capacity can be determined with significant errors when using incorrect shear parameters of soil.
