STATISTICAL ANALYSIS OF MARINE CLAY DEPOSITS

The main objective in this investigation was to find a dimensionless regression equation for the normalized undrained strength of Singapore marine days in terms of other normalized properties easily determined in the laboratory. Marine day properties from the various geographical areas in Singapore could not be grouped together for statistical analysis in their raw form. This necessitated normalization at the areal level and the application of the Kruskal-Wallis H-test on the residuals showed that the normalized variates can be grouped for further statistical analysis. The final forms of the stepwise regression analysis which involved the independent variables effective stress, bulk density, liquid limit, plastic limit, water content, plasticity index, and liquid index are cohesion equals 0.48 effective stress minus 0.2 water content and cohesion equals 0.52 effective stress minus 0.15 liquid index. The multiple correlation coefficients are 0.62 and 0.61, respectively. The validity of these equations has not been tested for overconsolidated and cemented clays.
