The seismic imaging method which surveys geological condition of ahead for tunnel face in the mountain tunnel are well known. However, it is not classified that this method can be applied to all of rock mass conditions, especially, in case of the rock masses including many fracture zones, it is important to research the degree of application of this technique because these rock masses are exciting many locations in Japan.
In this paper, this technique was applied on Hida tunnel construction site. As the result, it is clean that the geological conditions can be obtained by this method
