| 摘 要： | 采用通用有限元程序ANSYS,对某一桥墩与地基土层的相互作用进行了二维有限元分析,土体的本构模型采用ANSYS程序中的Drucker-Prager模型,土体边界采用粘—弹性边界人工边界,通过计算,得到了土结构相互作用对结构动力分析的影响以及土体性质、上部结构刚度不同时相互作用体系的动力特性。

| Abstract: | In this thesis, two-dimensional finite element analysis for dynamic soil-structure interaction is carried out. The general purpose finite element program ANSYS is used in the analysis. The Dru.cker-Pruger model of the ANSYS program is chosen as the constitutive relation of soil, and viscous-spring boundary of soil is used in calculation. Through inputting earthquake wave, the effect of soil-structure interaction is studied, and when the properties of soil mass or superstructure stiffness change is changed, the characteristic of soil-structure interaction will be calculated, |
