AN INTEGRATED APPLICATION OF TRANSIENT SURFACE WAVE AND SEISMIC REFRACTION METHODS TO TUNNEL EXPLORATION

As a high and new technique developed rapidly in recent years, the transient surface wave exploration technique is widely used in engineering exploration with excellent results obtained. With practical engineering examples, this paper deals with the collection of surface wave signal along with seismic refraction exploration, the utilization of surface wave components to make analysis during data processing, the thickness division of overburden bed, strongly-weathered bed, intermediately-weathered bed and weakly-weathered bed in combination with the refraction data, and mutual reflection and interpretation of the burial condition of the bedrock surface.
