used to plete the substructure construction，it has the fast advantage for construction.The centralized prefabrication for barrel type breakwater makes it mechanization， scale and standardization furthest，which can improve the environment of construction field，and be beneficial to the construction safety，quality and schedule control. According to these，it can be widely used in the construction of ports in China.The overall prefabrication scheme for the barrel type breakwater was described，meanwhile， the design and construction for steel formwork was introduced in detail. The engineering practice shows that the quality of the project meets the requirements of national standard， which ensures construction safety.
