The reasonable determination of ultimate bearing capacity is crucial to an optimal design of shallow foundations.
Soils surrounding shallow foundations are commonly located above the water table and are thus in an unsaturated state.
The intermediate principal stress has an improving effect on the unsaturated soil strength.
In this study, the ultimate bearing capacity formulation of strip foundations in unsaturated soils is presented by using Terzaghi’s theory.
The unified shear strength equation of unsaturated soils under a plane strain condition is utilized to capture the intermediate principal stress effect.
Furthermore, two profiles of matric suction are considered and a hyperbolic function of the friction angle related to matric suction (φb) is adopted to describe strength nonlinearity.
The validity of this study is demonstrated by comparing it with model tests and a theoretical solution reported in the literature.
Finally, parameter studies are conducted to investigate the effects of intermediate principal stress, matric suction, and base roughness on the ultimate bearing capacity of strip foundations.
Besides, the effect of strength nonlinearity is discussed with two methods representing the angle φb.
