The natural conditions such as wave and current in shallow sea area are relatively good，and the investment in conventional mound-type breakwater is relatively high. The vertical sheet pile breakwater structure can be considered for replacement to save engineering investment. Based on the actual project，the American standard is used to calculate the wave force in front of the sheet pile breakwater，and the wave force is verified by the physical model test. Finally，the inner force of each component and the overall displacement of the sheet pile breakwater are analyzed by the geotechnical finite element software PLAXIS. The analysis results show that：1）The inner force of each component of sheet pile breakwater is relatively small，and the corresponding type of prefabricated components can be used as the main structure of sheet pile breakwater.2）The overall displacement of sheet pile breakwater is controllable. 3）It is reasonable and feasible to use sheet pile breakwater structure in shallow water area.
