Abstract

In this study

a series of centrifugal model tests on bucket foundation were conducted by applying horizontal loads at different heights to investigate the development of ground deformation and the variation of resistance in bucket foundations. By the use of Abaqus finite element method

the changing pattern of the rotation center position and the transition from translation to rotation under the coupling effect of horizontal forces and moments in bucket foundations were revealed. A method was proposed to determine the development process of ground deformation in bucket foundations by analyzing the variation of the rotation center position. Furthermore

the reason for the expansion of the bearing capacity envelope under the coupling effect of horizontal forces and moments in bucket foundations was explained.
