Bearing Capacity of Shallow Foundations on Noncohesive Soils

A bearing‐capacity analysis of shallow footings and strip foundations subjected to axial, eccentric, and inclined loading is presented for noncohesive soils. The influences of load eccentricity and inclination, subsoil surface inclination, and depth and shape of foundation with regard to classical and new calculation methods are discussed. Comparisons of different formulas of bearing‐capacity factors, shape and depth factors, load and surface inclination factors, as well as values of these factors are presented. A methodology and analysis of model test results of both the writer and other authors are also presented and compared with different calculation methods, which show considerable underestimation of results with respect to classical calculation methods and reasonable agreement for new ones. The results of experiments for strip foundations and footings have been statistically evaluated and empirical formulas to determine Nγ values proposed. The quantitative data presented can be useful for verification of new bearing‐capacity calculation methods and practical engineering design.
