Abstract:The soilless cofferdam structure made of steel pipes of a tower of 110kV transmission line project from Dashan wind farm to Guhe town in Chuzhou was taken as the research background. The theoretical calculation and repeated mechanical analysis method were adopted to carry out systematic introductions on system selection and design method of this kind of cofferdam structure. At the same time, finite element method analysis and field monitoring were conducted on the stress state of this cofferdam structure. The analysis results show that the soilless cofferdam structure has well mechanical properties and reasonable design.

Keywords:soilless cofferdam; shallow water; stability; construction monitoring
