Abstract

In order to investigate and discuss a theoretical prediction on the seismic response of pile groups in soil-structure interaction systems, the dynamic characteristics of piles surrounded by soil ground due to earthquake type disturbances in addition to those excited by the loadings at the head of piles. This paper is concerned with a theoretical analysis which is based on the three-dimensional wave propagation theory to find dynamic interaction characteristics of elastic pile groups embedded in the viscoelastic soil stratum on a rigid basis, under external forces concentrated at the head of piles and uniformly distributed bedrock motion. In dealing with this complicated boundary configuration and exciting condition, the technique of superposition principle associated with the auxiliary problems is effectively applied. And, the governing equations in the domain of frequency and wave numbers reduce to the Fredholm type integral equations.

Dynamical Analysis of Soil-Piles Interaction Systems Under Earthquake Type Loadings

St. Louis, Missouri

In order to investigate and discuss a theoretical prediction on the seismic response of pile groups in soil-structure interaction systems, the dynamic characteristics of piles surrounded by soil ground due to earthquake type disturbances in addition to those excited by the loadings at the head of piles. This paper is concerned with a theoretical analysis which is based on the three-dimensional wave propagation theory to find dynamic interaction characteristics of elastic pile groups embedded in the viscoelastic soil stratum on a rigid basis, under external forces concentrated at the head of piles and uniformly distributed bedrock motion. In dealing with this complicated boundary configuration and exciting condition, the technique of superposition principle associated with the auxiliary problems is effectively applied. And, the governing equations in the domain of frequency and wave numbers reduce to the Fredholm type integral equations.
