説明

In order to manage issues concerning groundwater environment often created by construction of underground facilities, it is important to understand the hydro-geological features and potential transport pathways including fractures and matrices of bedrock. In this paper, the authors present the result of a field survey conducted in Tertiary sedimentary rock area with the aim of developing the exploration method for modeling hydrogeological structures and transport pathways. The results of this study can be summarized as follows:<BR>·Fractures can be divided into several groups based on their features, orientations, fracturing ages and others.<BR>·The specific fracture groups play a primary role in groundwater flow.<BR>·Rock matrices of sandstone and mudstone conduct small amount groundwater flow.<BR>Based on these results, a conceptual model of the water conducting features is discussed.
