Abstract：In the west of China,there are areas of giant-thick loess,deserts with unstable water table and giant-thick-gravel-piled piedmont,which is charac-terized by continuous near-surface velocity that using common method of controlling points of nearsurface survey and first breaks refraction method to control the distributed regularity of near-surface velocity and density is very difficult.For that reason ?on the basis of former “static corrections technique using continuous velocity model for inversion,,,the paper conducts inversion using continuous velocity model through fully and reasonably using near-surface survey data during the inversion and in combining with inflexion wave and refractions of first breaks on the shot records,which can accurately solve the structural parameters of near-surface and then compute final statics by integration.The analysis of real eases showed that the method described in the paper can better solve the static corrections in the west of China where the near-surface velocity continuously changed vertically.
