摘要
瑞利导波一般存在多个模式。假定检波器在各频率上接收到的信号为位移最大的那个导波模式,由此可得到一条理论频散曲线。将理论曲线与实测成果进行对比,其吻合程度很好。由此可说明,所用正演方法是正确可行的。
Rayleigh guided waves often have many modes. If it is assumed that the received signal in practice is the maximal displacement mode, we could obtain academic zigzag dispersion curves, and the academic curves are consistent with practical results according to the forward modeling results. All of those illuminate that the forward modeling method is correct and feasible.
