内容記述(抄録等)There are correlations between the residual strength and the soil index properties. The soil index are as follows; the clay fraction, Fclay, as related to physical property of soil particle, the pH and the salinity as related to chemical property of pore water, the liquid limit, wL, and the plasticity index, IP, as related to engineering properties of fine-grained soil. This study aimed for determining the residual strength from the soil index. To attain this purpose, the linear and involution functions are fitted to the relations. Additionally, the multiple regression analysis is carried out on our data and others, in order to examine correlation between the residual strength and the above index. For soils containing smectite dominantly, there are close correlations between the residual strength and the above index of the soils. Among the index properties used here, the ratio of the plastic limit to the liquid limit correlates most closely with the residual strength. The residual strength of such soils can be estimated based on both the index property and the mineral composition. It should be noted that the data used in the multiple regression analysis took account for mineral composition and type of laboratory test. As a result, the value of correlation coefficient improved in any combination of the explanatory variables. Therefore the residual strength can be estimated from Fclay, wL and wP of soil.
