A Precise Spatial Estimation Approach for Geotechnical Characterizations

Abstract

The geological survey using boring is often performed to obtain information for geotechnical parameters. Therefore, a lot of survey dates for geotechnical characterizations on ground have been accumulated. However, these data have not been put to practical use. The authors have performed the estimation of spatial distribution of the geotechnical characterization by the use of these data and a new information processing technique replacing by the empirical method used by the expert. In this study, a precise spatial estimation approach using a new algorithm improved the SOM with considering soil information is proposed. The efficiency is demonstrated by an example for estimating the spatial characterization of N value using actual boring data.
