摘要: 连续刚构箱梁桥是我国桥梁工程中最常的用桥型结构型式之一,已建成的此类桥梁中普遍出现了跨中下挠过 大.影响连续刚构桥跨中下挠因素较多并且复杂.归纳了影响连续刚构挠度的主要参数.以白果渡连续刚构桥为背 景,分析各种参数对连续刚构下挠的影响,在此基础上提出防治措施.

关键词: 连续刚构桥, 参数分析, 挠度

Abstract: Continuous rind frame bridge with box section is one of the most popular stmeture types in the bridge construction in China.Big widespread deformationin often appears in midspan of the brigdeS.Factors afecting deformation of the midspan of continues rigid flame bridge are plentiful and complex.The key factors afecting continuous rind frame bridge midspan deform ation were analyzed and summarized.By the basis of a continuous rigid flame stucture-Baiguodu Bridge,various parameter af ecting continues rigid flame bridge deform ation were analyzed.The prevention an d cure measures on this foundation are put forward.

Key words: continuous rigid frame bridge, analysis of parameter, deform ation
