ABSTRACT
The authors monitored the dynamic response of the surrounding rock mass at the excavation face of Taru-toge tunnel at the prefectural border of Shizuoka and Yamanashi prefectures, Japan built in connection route between New Tomei and Chuo Expressways. This monitoring study in the immediate vicinity of the tunnel face is probably the first one in the world so far within the knowledge of the authors. In this paper, the authors describe the several monitoring studies and the results obtained so far. They also discuss the implications of this study within the integrated framework of tunnel construction.
