| 摘 要： | 阐述了大跨度预应力混凝土连续梁桥的高程控制方法，分析了与高程控制相关的影响因素。并以陶赖昭松花江特大桥的高程控制为例，建立计算模型，运用有限元软件BSAS和前进分析法计算出各施工阶段的桡度，进而得出各悬浇段的预拱度，为高程控制提供依据。

| Abstract: | In this paper, the altitude control method of long span prestressed continuous frame bridge is stated and the influencing factors related to altitude control are also analyzed by using Taolaizhao Songhua River especially large-scale bridge as an example. The calculational model is established first, and the deformation of each construction phase is calculated with the finite element program BSAS in forward analysis method and the precamber that is the basis of altitude control of each cantilever construction segment is gotten. |
