Abstract

The main purpose of this paper is to investigate the ability of the surface reflection method, namely the sonic echo method and impulse response method, for flaw size assessment in a pile. Three dimensional axisymmetric finite element models were performed to investigate the effects of the flaw size, flaw depth-to-pile diameter ratio, and pile-to-soil stiffness ratio on the response of the surface reflection test. According to the results from the numerical simulations, some useful formulas for flaw size assessment in a pile are proposed, considering these factors simultaneously. Some other factors, such as the flaw length and pile diameter and length, were also discussed to show their effects on the proposed formulas.
