The sheet pile type wharf has the advantages of simple structure, simplicity and convenience in construction, few digging and filling, low manufacturing cost, strong adaptability to complex foundations and the like, and is widely applied to ports and hydraulic engineering. However, the sheet pile type wharf has the defects of poor structural integrity and durability and small bearing load, and is only suitable for small and medium-sized wharfs.

The gravity wharf has the advantages of good durability, mature technology, capability of bearing larger ship load and wharf ground load and the like. However, the gravity wharf has large dosage of sandstone materials, heavy structure and high requirement on foundation conditions.
The high pile type wharf distributes load and external force acting on the wharf to the foundation pile through the pile platform and transmits the load and the external force to the foundation pile. The high-pile wharf has the advantages of light dead weight, high prefabrication degree and small influence on environment, and is widely applied to ports with softer coastal foundations in China. However, the high-pile wharf has poor durability and weaker adaptability to load than a gravity type wharf and a sheet pile type wharf, the surface layer and the pile foundation of the high-pile wharf are exposed out of the water, the high-pile wharf is greatly influenced by wind and waves, the durability is poor, and the high-pile wharf is only supported by the pile foundation.
