Three kinds of crosshole geophysical measurements, which were seismic, radar and registivity measurements, were carried out using the same boreholes drilled in the rock mass of shale. Analysing the measured data with computer tomography techniques, the distributions of five physical properties were obtained, which were registivity, seismic velocity, attenuation of seismic wave, velocity and attenuation of electromagnetic wave. The structure and the condition of the investigated rock mass are inferred from all the analysis results キーワード(英): - 記事区分 - 区分    委員会論文集
