The method of steel sheet pile cofferdam with sequential construction is broadly applied in many projects of road, bridge and hydraulic engineering. Comprehensive technology of steel sheet pile cofferdam with inverse construction technique in deep water is proposed, which could be used to conquer weaknesses of steel sheet pile cofferdam with sequential construction, such as large deformation, low global stability, high construction risk and restricted water depth. Design, analysis and construction of steel sheet pile cofferdam with conversable construction technique in deep water are given in detail, deformation and force situation of steel sheet pile cofferdam in the construction progress is monitored. The technique could preferably satisfy the requirement of safety and economy in engineering construction.
