In Egypt Port Said Container Terminal Phase II,pile and diaphragm wall combined wharf structure was successfully applied.When calculating the displacement of the structure under seismic condition,due to the obvious 3D structure feature,a 3D model was adopted to correct the two-dimensional model under a typical case,then the corrected two-dimension model was used in various cases；three typical seismic waves were chosen with two seismic standards,i.e.Level 1 and Level 2,for the dynamic analysis,and the results showed that the structure satisfied the requirement under the case of earthquake.
