Inspection and Revision of the Rayleigh Wave DispersionCurves via a Wave-Field Simulation Method

Objective The separation of higher modes from multimode dispersion data is the key problem in Ray-leigh wave inversion.The complexity of energy distribution in real-world data leads to a difficulty inmode separation.This study developed a new method to confirm dispersion data using a forwardingwave-field.The results of numerical and real world experiments demonstrated that this method is ef-fective for confirming the dispersion data interpretation and improves dispersion extraction data quali-ty.
