探究预应力箱梁施工的控制要点

The Control Points of Prestressed Box Girder Construction

预应力混凝土连续箱梁施工技术,由于跨越能力大,施工方法灵活,适应性强,结构刚度大,抗震能力强,通车平顺性好以及造型美观等特点,在桥梁中被广泛应用。本文结合了实际工程,探讨了现浇预应力箱梁施工技术及施工控制要点,以供同类工程施工项目参考。

The construction technology of prestressed concrete continuous box girder, with the characteristics of large span capacity,flexibility, adaptability, structural stiffness, seismic ability, traffic convenience and beautiful appearance, etc., has been widely used in the bridge. This paper combined with the practical engineering, discussed the cast-in-place prestressed box girder construction technology and the construction control points, providing references to similar projects.
