| 摘 要： | 对桩和近域土体采用有限元分析,桩土之间加设接触面单元来模拟桩土之间的相对沉降,对远域土体采用无限单元来模拟。混凝土单元和无限单元采用弹性分析,近域土体采用K~G模型及Duncan-zhang(E~μ)模型来模拟九桩低承台群桩的工作机理,并与实测值相比较、分析,证明方法是合理的。

| Abstract: | In this paper, the finite element analysis is adopted to imitate the piles and the surrounding soil; Between the pile and the soil, a joint element is designed to imitate the relative settlement while the infinite element is used to imitate the surrounding soil. Fortran language is used to compile a corresponding nonlinear analysis program. We use elastic analysis method for concret elements and infinite elements, E~U model for surrounding soil. an example is used for analysis, the result shows that the method adopted is reasonable. |
