| 摘 要： | 经验法设置大跨径连续刚构桥预拱度存在诸多问题。通过对连续刚构桥挠度的分析，结合《公路钢筋混凝土及预应力桥涵设计规范》，提出了设置最大预拱度的长期增大系数法及按余弦函数曲线分配预拱度的方法。经实例验证，计算结果与经验范围相符合，且合理有据，值得推广应用。

| Abstract: | At present, the experience method of installing the camber has many problems. In this paper, the authors analyze the deform proceeding of Continuous Rigid Frame Bridge. According to the new codes for bridges and the finite element analysis result, the authors put forward a method of the long - team addition coefficient to install the camber and distribution of camber according to cosine line. The examples prove that this method meets the experience result very well, and the method has more evidence and stringency. The research achievements deserve energetically application and dissemination. |
