Combining with the engineering examples,the paper adopts the cast-in-place support method to construct the 900 t prestressed simply-supported box girder by analyzing and comparing the cast-in-site simply-supported box girder support scheme,and indicates from the foundation treatment,the support erection and prestress,the construction of box girder,and the prestressed tension,so as to accumulate experience for similar projects.
