地盤データベースを用いた海底地盤特性の評価

Abstract

Boring data and laboratory test results are essencially important to design every civil engineering structures. In particular, we should clarify the engineering properties of the sea bed in the case of the waterfront development. The Osaka Bay sea bed database (SBDB) has been established in order to handle the many geotechnical data conducted by many organizations relating to the Osaka Bay development.In this paper, we try to evaluate geotechnical properties of the sea bed by SBDB.Firstly, we propose the evident of the equivalent soil layer divided by ten thin layers of each clay soil layer. Secondry, the settlement of an actual man-made island was calculated by use of SBDB, and finally, the measured settlement data were compared with the calculated values.
