| 摘 要： | 刚构桥箱梁下缘曲线幂次的合理选取，是此类桥梁设计的重点。通过对大跨径连续刚构桥（主跨为220m）箱梁下缘曲线的幂次进行调整，并运用MIDAS／CIVIL软件对整桥进行建模和结构分析，得出不同曲线下结构的内力分布。经过比较分析，得出箱梁下缘曲线的合理选取范围及建议，对连续刚构桥梁主梁设计参数的合理选取具有实际指导意义。

| Abstract: | Reasonable selection about box girder curve of the lower edge is important in the design of this type of bridge. By selecting continuous rigid frame bridges （main span of 220m）, making several rectifications in the lower edge of the box-girder curve and using MIDAS/CIVIL in modeling and structural analysis, the corresponding load distribution of different curve structure is obtained. After comparative analysis, this paper gives us the scope of reasonable selection about box girder curve of the lower edge. It is a good guide for a reasonable selection about main design parameters of continuous rigid frame bridge. |
