Application of shallow three-component seismic prospecting technique to the investigation of subsurface fractures and hidden holes under highways in western China

This paper involves the hazard of geological defects,addresses the progress of shallow three-component seismic prospecting and its application in geological hazard investigation of highways.Through practical examples and the effect of application in highway geological hazard investigation,the three-component seismic prospecting technique is proved a modernized prospecting technique and becomes a part of systemic project of geological hazard control.It will play a very important role in geological hazard investigation.With its prominent characteristics such as fast,comprehensive,accurate and economical,the shallow three-component seismic prospecting in many areas especially in sensitive areas can reach non-destructive exploration and supply scientific proof for construction project of geological hazard control.
