Abstract Research purposes: Based on the construction of the high pile cap of the Qingdao Bay Big Bridge, the analyses of the load on the reinforcement concrete box cofferdam are made with general finite element analysis software. With the finite element simulation analysis of the actual working state of the R. C. box cofferdam, the data are obtained for the purpose of optimizing the construction technology场decreasing the structure dimension and hoisting weight as much as possible.
Research conclusions: The simulation load analysis to the box cofferdam with solid65 element can solve the unit freedom coupling of the reinforcement concrete mixed materials effectively and perfectly simulate the dimension, space location, connecting conditions, edge conditions and space carrying state to provide high exact value model for the structural optimum and high exact value for the construction.
