Abstract

This study aims to develop the method to estimate permeability distribution in crystalline rock mass from cross-hole P-wave tomography by using the relationship between frequency-P-wave velocity dispersion and permeability. We operated laboratory tests to measure P-wave velocity with various frequencies for granite specimen and cored specimen of granitic gneiss with breccia zone. The results showed the dispersion for all specimens, and the characteristic frequency of the dispersion relates to permeability. Based on these results, we discuss the application of this permeability estimation method to field scale. We proposed a method to combine cross-hole P-wave tomography and borehole packer permeability test.
