Numerical Studies of the Bearing Capacity of Shallow Foundations on Cohesive Soil Subjected to Combined Loading

摘要

This paper presents the results of three-dimensional finite element analyses of circular foundations resting on the surface of homogeneous, purely cohesive soil. The predicted ultimate response of the foundations to combined vertical, moment, and horizontal loading is compared with other available theoretical predictions. A three-dimensional failure locus is presented for these foundations, based on the numerical predictions. An equation that approximates the shape of the failure locus is also suggested, and this provides a convenient means of calculating the bearing capacity of circular foundations resting on the surface of a uniform clay and subjected to combined loading.
