以一维波动理论为基础 ,利用计算机仿真程序 ,对运用低应变反射波法检测桩身完整性的过程中 ,土层的分层状况对检测波形的影响进行了讨论。结果表明 ,不同的土层状况对波形有不同的影响 ,而且具有一定的规律性。 Based on the one-dimensional wave theory, the influence of the stratification of soil layer on the detection waveform is discussed in the process of using the low-strain reflection wave method to test the integrity of the pile body by computer simulation program. The results show that different soil conditions have different effects on the waveform, and have certain regularity.
