We acquired the water permeation properties and also mechanical characteristics of the altered specimen that produced by permeation or immersing as the fundamental data.

In order to understand groundwater flow in Japan, it is important to know the hydraulic gradient and the sea / fresh-water boundaly. In particular, the hydraulic gradient is required to estimate very slow groundwater flow at depth. Also, the location of the sea / fresh-water boundary is required to characterize groundwater flow near the coast. In this study, we obtained the above-mentioned data from a number of published papers, and tried to find the suitable method to help evaluating the groundwater flow model.

High differential pressure condition is usually encountered around the adits and shafts in deep underground rock mass. As the depth becomes larger, the magnitude of differential pressure becomes greater. However, most of the existing investigation techniques are seldom applicable to the high differential pressure conditions. For surveying the hydrogeological and geochemical characteristics of deep underground rock mass, the development of the appropriate investigation techniques is highly encouraged.The purpose of this preliminary study which was executed the last year was to evaluate the applicability of the existing investigation techniques to the geological conditions in deep underground rock mass. In this year, the purpose is to evaluate the applicability of the existing investigation techniques to the numerical analyses for the hydrogeological structure of deep underground rock Mass.
