| Abstract: | The approach spans to the Xia-Zhang Bridge are mainly composed of precast segmental box girders. This paper in- troduces the technical features, such as procedures for girder fabrication and erection, design equipments of formwork system and gantry for span erection, the geometric control technology of precasting segment girder with transition curve section. The construction and installation process complies with the requirements and the structure is well stressed, providing reference for similar projects. |
