In order to overcome the harsh natural conditions and speed up the construction of offshore reefs,it is necessary to find a new rapid land formation technology. In order to reduce site operation and rapid construction,this paper studies the feasibility and adaptability of rapid land formation technology in shallow draft caisson structures from the aspects of caisson structure,functional requirements and rapid land formation implementation method.By optimizing the caisson structure and analyzing the field conditions,the light caisson which can meet the requirements of drag-and-carry draft and the use of function is obtained,and the method of non-leveling installation of the caisson on the base bed is developed.The feasibility of the key technology is verified through the light concrete caisson precast and the reverse top lift leveling test,which provides data support for the later application of the technology.
