The author proposes a general formula for calculating the load-bearing capacity of a foundation based on several factors. Specifically:
1) The formula depends not only on the properties of the soil but also on the shape, size, depth, and distribution of pressure of the foundation area.
2) It is proposed to calculate the effective area of the foundation by multiplying each foundation element by a factor related to its depth and eccentricity.
3) The original formula from Terzaghi was modified by multiplying each term by a factor related to the properties of the soil as well as factors related to shape, size, and pressure distribution.
