【Abstract】 The velocity respondeuce at the top of the pile during the one-dimension stress wave transfering because of the change of the wave impedance was deduced briefly and the numerical simulation calculation was done by a femlab power finite element program.This supplied a possibility for analyzing the aff-ect of various defects to the velocity curve under the ideal situation.更多还原
