预应力水平曲线转换梁属压弯剪扭复合受力构件，其设计与施工困难。而国内外对之研究甚少。因此本文在对预应力曲线架的受力特点和预应力配筋形式进行研究的基础上，结合实际工程对预应力箱形和矩形截面曲线转换大梁结构进行了试验研究，并提出预应力曲线转换梁设计与施工时应注意的事项，以供参考。
The prestressed horizontal curve conversion beam is a kind of composite component of the bending, torsion and torsion. Its design and construction are difficult. However, few studies have been done at home and abroad. Therefore, on the basis of the research on the stress characteristics of prestressed curved frame and the prestressed reinforced form, the paper studies the prestressed box girder with rectangular section and the prestressed concrete girder with practical engineering, Design and construction of the beam should pay attention to the matters for reference.
