Abstract
Three-dimensional finite element analysis in time domain on dynamic soil-pile-structure interaction of a practical engineering is carried out in this paper. General-purpose finite element program ANSYS is used in the analysis. Commonly used equivalent linearity model is chosen as constitutive relation of soil. Viscous boundary of soil is implemented in ANSYS program. The influences of parameters, such as soil property, excitation, the rigidity of structure and buried depth, on dynamic characteristics, seismic response and interaction effect of SSI system are discussed.
