The sheet-pile wharf with separated relief platform is mainly composed of the front wall,the anchorage wall,the tie rod and the unloading platform system.The system bears the load from the wharf upper structure,which can reduce the front wall load and increase the excavation depth of the basin.Numerical simulation for the stacking process of this new type of wharf structure is the basis of the numerical simulation for the wharf.Numerical simulation by software FLAC3D is carried out to discuss the stress and deformation characteristics and the earth pressure distribution of sheet pile wharf with separated relief platform during excavation and stacking.Based on the comparison between results of prototype observation data and centrifugal model test,the rationality of the stacking simulation method proposed here is verified.
