3D effect is analyzed and the average velocity of wave propagating in the pile, which mainly influences inverse interpretation, is discussed. Finally, the theory results are verified by model experiment. It is shown that 3D results have the same phase with ID results. The pile radius, the duration of impulse, the ratio of hammer radius to pile radius and shear velocity of the soil around the pile have influences on 3D effect. The best position of receiver is 0.55R from the pile center. The average velocity of wave propagating in the pile reduces due to transversal inertia effect and 3D effect.
结果表明:三维曲线与一维结果在相位特征上一致;波场图直观地反映了波在桩中的传播规律;三维效应与桩径、激振脉冲宽度、相对激振半径及桩周土剪切波速有关;传感器放在0.55R处可以得到干扰较小的信号;三维效应和横向惯性效应的存在会使桩中的波速减小,土的性质对波速影响不大;反演精度与缺陷的性质、激振条件有关。
