摘要

开展系列筒型基础离心机试验,通过在不同高度对筒型基础施加水平荷载,研究地基的变形发展过程和筒型基础的抗力变化规律,进而结合Abaqus有限元分析,揭示筒型基础在水平力和力矩耦合作用下,转动中心位置的变化规律及运动模式由平动过渡到转动的过程,提出通过转动中心位置变化确定筒型基础地基变形发展过程的方法,并解释筒型基础在水平力与力矩耦合作用下出现承载力包络线向外扩张的原因。

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.
