On construction technique for erection of 700 t prestressed simply supported box girder along Wuhan-Huangshi special passenger line

Taking the erection of 700 t prestressed simply supported box girder along Wuhan-Huangshi special passenger line as the example, the paper sums up the erection equipment and structure characteristic of the box girder and its performance, and illustrates the construction craft of the erection for the box girder and the key points for bearing’s perfusion, so as to accumulate relative experience and direct the engineering practice.
