Expansion joint of a bridge is a weak part of structure, it leads to early structure destroy and reduces the bridge life. The paper put forward a new type of Jointless Bridge --- Semi–Integral Abutment Jointless Bridge, and its theoretical model was built. An engineering of four spans 100m length Prestressed Concrete Semi–Integral Abutment Jointless Bridge was analyzed, and results that its mechanical performance is so excellent that it should be wide applied in bridge engineering.
