GEOTECHNICAL PROPERTIES OF ARIAKE CLAY IN SAGA PLAIN-JAPAN

Abstract

This paper describes the geotechnical properties of Ariake clay found in Saga plain, a lowland in north of Ariake sea in Kyushu, Japan. It is attempted to discuss the geotechnical properties of Ariake clay up to the depth of 20 meters by using the data of 110 exploratory boreholes drilled in different places of Saga plain. Simple regression equations are developed for some index properties and multiple regression equations are developed to estimate unconfined compression strength, compression index, compression ratio, and preconsolidation pressure from index properties. The efficiency of equations are discussed statistically by using the analysis of variances.
