AbstractAbstract
[en] A precise estimation of the permeability distribution of rock mass is one of the issues for making use of deep underground. One of the investigation and analysis methods proposed is a cross-hole hydraulic test and a tomographic analysis. As to a tomographic analysis, a time-domain difference calculation commonly sued needs much time. For a fast calculation, Laplace Transform Galerkin method is applied which translate a time-domain problem into a frequency-domain problem. The feasibility study of a cross-hole sinusoidal hydraulic test is also carried out by three-dimensional numerical experiment. (author)
