摘　　要： 预应力混凝土结构已被逐渐广泛地应用于工程中,而预压力所产生的拱度正好可以抵消荷载作用下梁板所产生的挠度,显然这对结构是有利的。然而如果拱度过大,对于桥梁工程来说,造成公路桥梁路面不平顺,导致行车不顺畅,产生负面效果。因此,如何控制好结构的拱度也是一个亟待解决的问题。文章主要从拱度的成因、结构的材料等几个方面来谈谈对结构拱度的控制。 Prestressed concrete structures have been increasingly widely used in engineering, the pressure generated by the pre-camber is just enough to offset loads generated by the deflection of slab, it is clear that the structure is favorable. However, if the arch is too large, for the bridge project, it caused road and bridge irregularities, resulting in traffic and negative effects. Therefore, how to control the structure of the arch is a serious problem. From the causes of not smooth arch, the structure of the material, this paper talks about several aspects of the structure camber control.
