The test result of multi-step consolidation creep of marine soft soil shows that the consolidation of the soil has nonlinear,irreversible and time dependent behaviours. Furthermore, a new concept of time-effect coefficient of creep consolidation is proposed and a nonliear constitutive relation which may reflect the one-dimensional consolidation creep of marine soft soil is established.
