地盤調査方法の過去10年を振り返って(<小特集テーマ>地盤調査法の変化・変遷-地盤物性調査と力学試験-) Review of Geotechnical and Geoenvironmental Investigation Methods for the Last Decade(<Theme>Technological Changes of Geotechnical Investigation-Material Properties Profilings and Mechanical Testings-)
The Japanese Standards for Geotechnical and Geoenvironemental Investigation Methods which is called the "JGS blue book" was revised in June, 2004. The publication includes the progress and advances in geotechnical and geoenvironmental investigation techniques. However, the standardization of newly developed techniques is often delayed, because it takes time for complicated standardization processes and examination. This report reviews the progress of the investigation techniques in relation to standardization for the last decade, and focuses on the modification of standards which have been established for a long period, the progress of techniques sociated with the new technologies of sensors and communication systems, and the requirements by the government, society and community.
