| Abstract: | Based on real project,the design and key construction technology in large double-wall steel cofferdam are introduced.Through the clever use of cofferdam cavity,the cofferdam＇own buoyancy is changed to make it float into the water by itself.Buoyancy and anchorage of auxiliary are used to real-ize the positioning without guide ship.The result shows that the steel cofferdam positioning is accu-rate and the precision meets the requirements. |

| Keywords: | double-wall steel cofferdam from floating into the water anchor auxiliary unguided ves-sel positioning |
