| Abstract: | The unconsolidated undrained dynamic behaviour of soft clay was studied. On the basis of cyclic triaxial tests, a reasonable means describing the accumulative deformation of soft clay under cyclic loads was suggested. By this means, the relationship of the accumulative deformation and physical parameters such as static stress, cyclic stress, number of load cycles had been expressed in an unified way. All this has furnished feasible data for researching the deformation behaviour of marine soft clay foundation and its bearing capacity. |

| Keywords: | soft clay accumulative deformation cyclic strength |
