摘要
通过三维有限元的数值分析方法 ,建立桶形基础三维有限元模型 ,并与试验结果比较 ,验证了三维有限元程序功能的可靠性。通过三维有限元的数值模拟 ,研究了在水平荷载作用下不同土体特性对桶体变位。
In the paper, three dimension(3D) finite element model of bucket foundation is established by 3D finite element method and its reliability is validated by the comparison with the test results. The influence of different soil characteristics on bucket displacements, distributions of earth pressure along outside of bucket under horizontal forces is studied by 3D FEM numerical simulation.
