The industry urgently needs economic exploring methods to check and find the underground cave, with physicalmechanical properties different from the around medium. One of the exploring methods is the use of the Rayleigh surface wave. The Rayleigh surface wave theory and the dispersion characteristics in transmission are discussed in this paper, and the Rayleigh surface wave field characteristics are simulated by the finite element method. Shaking with different main frequency epicenters, some models are established with dissimilar depth and size, and tallied up the results of the kinetics and the dynamics characteristics of the Rayleigh surface wave. Using the experiment result of the Rayleigh surface wave exploring methods in Lafayette University's gymnasium from southeast to northwest, for instance, this methods in checking and finding the underground cave are discussed.
