摘要

With the excavation work of a tunnel intersecting underground with a headrace already in place at a clearance of 17 meters, the authors have provided vibration control by constructing a core-contracted pilot drift using a TBM and the lump blasting electronic delay detonators. In this study, the effectiveness of the method in question has been confirmed by tvarious measurements and analyses and a vibration prediction equation has been examined.
