Numerical Assessment of Factors Affecting Reflection Pulse Based on Low Strain Testing of Piles

The propose of this paper is to achieve and analyze kinds of velocity versus time curves through changing the parameters of pile respectively includingmesh density, impulse width,Receiving point, and modulus of soil based on finite element numerical simulation. Then, summarize the factors which influence reflectionpulse characters and influencing regularity of the reflectionpulseto provide reference of the real project detection.
