It　is　a　difficult　problem　to　purify　the　Leibo　signal　from　the　seismic　record.　In　order　to　purify　the　Rayleigh　wave　signal　from　seismic　records,　a　new　method　for　purification　of　Rayleigh　wave　exploration　signal　is　proposed,　which　is　based　on　the　combination　of　multiple-filter　technique　and　time-frequency　filtering　of　generalized　S　transform　(GSTTF-MT).　GSTTF-MT　calculation　is　described　in　this　paper.　It　illustrates　that　the　GSTTF-MT　can　be　effectively　applied　to　the　Rayleigh　wave　purification　through　the　simulation　experiments　and　engineering　examples.　After　analyzed　and　compared　the　advantages　and　disadvantages　of　GSTTF-MT　and　other　methods.　In　conclusion,　the　method　of　GSTTF-MT　is　reliable　and　stable,　and　the　experience　and　conclusions　can　be　for　reference　to　extraction　of　Rayleigh　wave　dispersion　Curve　in　practical　engineering.　©　2018,　North　Atlantic　University　Union.　All　rights　reserved.
