Abstract

Abstract

Based on the one-dimension stress wave theory,the low strain dynamic test of concrete pile whose top is restricted or not is studied by finite element explicit analysis method. The dynamic tests of top-restricted concrete pile are affected not only by the soil around pile,but also by the upper structure,and the signal of 3D effect reflected by the pile is stronger. Then,the interference of the upper structure is filtered through signal progress. Finally,the simulated curves are in good agreement with those obtained from field measurements. So the simulation of concrete pile dynamic test is reliable and the conclusion may be a guidance of increasing the accuracy of the low strain dynamic test of concrete pile.
