| Abstract: | Based on theory of Beam on Elastic Winkler Foundation, the mechanism of pile soil pile interaction has been analyzed. By inducing the concept of interaction coefficient, a method was proposed to estimate the equivalent dynamic stiffness matrix of the structure on the layered site. The characteristics of the dynamic effects of pile_group have been demonstrated by two actual examples. And the differences between the examples were also developed. |
