Application and Development of the Super-large Diameter Column Foundation of Bridge

With the increase of span, the structural form of bridge foundation is seeking for development. The super-large diameter column foundation has become one of the best alternatives for bridge substructures. With the development of bridge foundation, the application status of the super-large diameter column foundation is combed. Its construction methods are briefly summarized, such as artificial digging, embedding prestressed pipe and super-large diameter bored pile, which promote the application of single column foundation. In the future, engineers can also get inspiration from the offshore wind turbine and seek new development ideas. Combined with the application of super-large diameter column foundation in the cross-sea bridge at home and abroad, the unique advantages and the problems needed to be solved in the practical application of the super-large diameter column foundation of bridge are pointed out, and its development is prospected.
