A new method for predicting a geological condition beyond a face in tunnel is developed by using a hydraulic drill. This method is based on the crosshole seismic exploration technique. Boreholes for the source and the receiver are drilled by a hydraulic drill. A blow by a hydraulic drill is used as the source. According to the in-situ experiment in a tunnel, it is recognized that the seismic velocity is estimated accurately by making an appropriate correction on the measured travel time of the first break when the source is a blow of a hydraulic drill. キーワード(英): - 記事区分 - 区分    委員会論文集
