Abstract
The jacking of cantilever before key segment closure has been introduced to offset the long term forces caused by creep and shrinkage. In this paper, the behavior of structural system with the jacking force in approach bridge of Incheon Bridge was reviewed. The introduction of jacking force effectively offset the long term horizontal forces and allows economic substructure member design.
