Summary:The system which explores geological structures in front of the cutting face on mountain tunneling is developed. This system has explored the geological structure by means of Rayleigh wave. The following points have been examined in case of loading Tunnel Boring Machine (TBM) with this system. 1. The method of setting the exciter to the cutting face. 2. The method of arranging the exploring equipments to the cutting face. It is possible to prevent in advance the troubles caused by the geological struc tures, for exeample fault fracture zone in applicating this system to the tunneling. Therefore, safety and rapid construction will be possible.
