An Effective Stress Framework for Bearing Capacity of Shallow Foundations in Unsaturated Soils
This manuscript presents a theoretical framework to model the bearing capacity of shallow foundations on partially saturated soils. The conventional Vesić bearing capacity equations for shallow foundations are modified to include the effects of matric suction and varying water contents and unit weights within the effective stress framework. Suction and water content are related through the familiar van Genuchten constitutive model, thus linking suction stress to density for a homogenous soil skeleton. A closed-form solution that modifies the overburden, unit weight, and cohesion terms in the conventional Vesić equation is proposed. Bearing capacity predictions from the modified equation for shallow foundations are compared to results from model- and full-scale load tests in partially saturated soils presented in the literature, showing good agreement with observed response.
