In order to predict the deformation characteristics from the results of soundings and convenient soil tests, relationships between the deformation characteristics and physical-mechanical properties were studied by using multiple regression analysis in which the soil test results for the samples obtained from clay deposit in Osaka and Hyogo prefectures were used. This analysis is based on the concept that the mechanical properties of soils are characterized by their kinds and states. The conclusions are summarized as follows.
(1) The validity of the concept employed here can be quantitatively proved by the multiple regression analysis.
(2) The deformation characteristics of soils, which are the modulus of deformation, consolidation yield stress and compression index, are predicted more accurately by using both the shear strength and physical properties of soils.
(3) The characteristics of e-log p curves are explained reasonably by the results of the multiple regression analysis in this study.
