Abstract

The consolidation and permeability characteristics of the Singapore marine clay were investigated by laboratory and in situ tests. The coefficient of consolidation and the coefficient of permeability of the soil in both the vertical and horizontal directions, c_v and c_h and k_v and k_h, respectively, were determined by oedometer, constant rate of strain, Rowe cell, piezocone (CPTU), flat dilatometer, self-boring pressuremeter (SBPT), and BAT permeameter tests. The c_h value of the clay was also back calculated from field monitoring data. Comparisons of the results obtained by different methods indicate that the c_h value determined by CPTU is generally in good agreement with that by Rowe cell tests, and the c_h value determined by SBPT is often the highest among all the measurements. The back calculated c_h value is lower than that measured by other tests, which could be possibly due to the smear effect incurred during the installation of vertical drains.
