Installation resistance and bearing capacity of a shallow skirted foundation in clay

Installation resistance and bearing capacity of a shallow skirted foundation in clay

Installation resistance and uniaxial undrained compression capacity of a shallow skirted foundation embedded in normally consolidated and lightly over consolidated clay have been investigated in a series of beam centrifuge tests. Measured installation resistance is consistent with simple analytical predictions giving interface friction factors in good agreement with predictions from cyclic T-bar tests. Measured bearing capacity without preloading is in good agreement with theoretical solutions. The increase in operative shear strength from preloading is higher for the skirted foundation when compared with numerical data and experimental results for surface foundations. The study highlights the effects of consolidation history on the installation and undrained bearing response of a shallow foundation in clay.

Abstract

Installation resistance and uniaxial undrained compression capacity of a shallow skirted foundation embedded in normally consolidated and lightly over consolidated clay have been investigated in a series of beam centrifuge tests. Measured installation resistance is consistent with simple analytical predictions giving interface friction factors in good agreement with predictions from cyclic T-bar tests. Measured bearing capacity without preloading is in good agreement with theoretical solutions. The increase in operative shear strength from preloading is higher for the skirted foundation when compared with numerical data and experimental results for surface foundations. The study highlights the effects of consolidation history on the installation and undrained bearing response of a shallow foundation in clay.
