Abstract

Active source surface wave prospecting method which is applicable to technical field of geological prospecting, comprising: collecting, by detector at preset station, surface wave data transmitted from seismic source; calculating to obtain dispersion energy graph on basis of vector wave-number transformational algorithm and according to surface wave data; extracting dispersion curve from dispersion energy graph, dispersion comprising base-order surface wave dispersion curve and high-order surface wave dispersion curve; establishing initial stratigraphic model according to base-order surface wave dispersion curve and high-order surface wave dispersion curve, performing, according to initial stratigraphic model, joint inversion on base-order surface wave dispersion curve and high-order surface wave dispersion curve to obtain inverting data of stratigraphic texture. Accuracy of surface wave prospecting result is effectively improved. Further provided are surface wave exploration device and terminal device.
