EXPERIMENTAL EXPLORATION OF SEISMIC TOMOGRAPHY IN SOFT ROCK MASS INCLUDING TERTIARY FAULT ZONE

抄録（英）：
We carried out the experimental exploration of seismic tomography using three boreholes of about 30 meters depth in the Tertiary system of pyroclastic rocks and mud stone. We tried to reconstruct the already well-known fault zone in this Tertiary system by tomographic technique. Measurement data were analyzed by BPT, ART and SIRT methods. Consequently (1) main fault ( 1 meter width ) and secondary fault ( 30 cm width ) accompanied with weathering zone could be reconstructed by ART and SlRT methods, (2) distribution of travel time error in each cell is important factor for the judgment of convergence by iteration, (3) velocity of elastic wave calculated by previous-existed technique was sometimes different from those of tomography, and (4) result of tomography reflected those of soil and rock tests concerning fault materials and their host rock.
