The basic characteristics and creep properties of undisturbed and remolded soft dredger fills treated by vacuum preloading from reclamation site in Binhai New Area of Tianjin

are studied. The results show that the soft dredger fill treated by vacuum preloading not only has structural characteristics but also has creep properties; the structural characteristics play a very important role in creep properties of the soil. Through updating the modified Cambridge model

it can consider the impact of structural characteristics; then making it as yield function of creep model

a semi-empirical and semi-theoretical creep model considering the impact of structural characteristics is established. The calculated results show that this model fits the fact of structural soft dredger fill

so it can be put into engineering practice.
