Abstract：Land reclamation is an important way in solving the land-scarce issue for construction in coastal areas. The stress and deformation properties of reclaimed port ground under the action of container load are insufficiently studied. A numerical simulation is conducted using FLAC3D to establish a full-scale model as the field test conditions. The pavement is simulated by the elastic model and the ground is simulated by the M-C model. The additional stresses, vertical strains and lateral displacements are analyzed. The simulated results show that the ability of stress dispersion of medium-coarse sand is better than that of mucky clay. Within the loading region, the additional stress decreases with the increase of depth, and the maximum lateral displacement occurs at the top of mucky clay. Outside the loading region, the additional stress slightly increases with the increase of depth, and the location of the maximum lateral displacement gradually goes deeper. Finally, parametric studies on the elastic modulus of medium-coarse sand and mucky clay are presented.
