地盤構造解析へのボーリングデータベースの応用

抄録

We examined the characteristics of the ground structure of the Karoeoka, Kyoto, Osaka basins and the Kumamoto Plain based or the boring database system of the areas with respect to: distribution of facies at the same elevations and depths; three dimensional projection of geological columns; distribution of the upper surface depth of pyroclastic flow deposits (ASO-4) ; calculation of appearance percentage of clay, sand and gravel at the same elevations and at 0.5m-intervals; Markov matrix which quantifies the transitions of facies: and distribution of N values in clay or sand at the same depths.
