Investigation of Simplified Integrated Model for Soil-Pile Dynamic Interaction System

Abstract:

A simplified integrating model is developed for soil-pile dynamic interaction system under seismic loading. Different from previous work, this simplified model constructs the whole system stiffness matrix by combining the stiffness matrix of pile and near region soil system according to the volumetric ratio of pile group and soil system. This simplified model can avoid deviation brought by previous soil-pile surface model and can felicitously simulate the co-working mechanism between soil and piles. The feasibility of the proposed approach is assessed by comparing with in-site observation result of real project.
