| 摘 要： | 利用空间有限元法分析了单箱双室钢筋混凝土连续箱梁剪力滞效应，分别计算了自重作用及活载作用下跨中截面与支座处截面的正应力分布规律及剪力滞系数，并将采用有限元分析得到的翼缘有效宽度与规范中的有效宽度规定进行了比较，以期为同类桥梁设计提供参考。

| Abstract: | The shear lag effect of reinforced concrete continuous girder with one box double cells is analysed by spatial finite element method, the normal stress distribution and shear lag coefficient at mid-spand and bearing span under selfgravity and live load are also calculated in this paper, At last the effective width of flange according to finite element analyse and standard is compared, the research results could be taken as reference to other bridges design. |

| Keywords: | continuous box girder with one box double cells shear lag effect finite element analysis eftective width |
