In soft soil area, the large displacement usually occurs between the sluice pier and the wing, which results in seal failure and endangers the sluice's safe operation. Thus, in this paper, the whole sluice model was established with finite element method, and for the soil body, using the Drucker-Prager constitutive model considering soil body creep law. Thus, the reason of the displacement and the influence of connecting empty container in gate side on wings and pile foundation were explored. The results indicate that the groundsill linking empty container transition sluice and sea wall has improved the stress conditions of the pile foundation and effectively controlled displacement of the wing. Further, a reasonable empty container size can not only effectively control displacement, but also avoid project investment waste due to excessive size.
