预应力混凝土连续箱梁加固研究

hrough the long-run prestressed concrete girders increased more widespread phenomenon of cracks and flexibility. With practical engineering examples, this paper mainly introduces the crack for repair, paste armor plate, sticking carbon fibre sheet methods, steel truss, the external prestressing cables etc, and introduced in detail the construction method of reinforcement in the coordination, combined with engineering examples introduces reinforcement measures of cases in the normal operation of the upper bridge, and illustrats the specific application in engineering practice and the effect.
