结合弯箱梁桥的特点，采用空间板壳有限元法分析了在对称集中荷载及均布荷载作用下曲率半径、宽跨比等结构参数对连续宽体曲线箱梁桥剪滞效应的影响，与同类研究结果对比发现剪力滞对宽体曲线箱梁的影响更为明显。编制了供设计参考的四跨宽体连续梁桥剪力滞系数计算表，为完善现行桥梁规范中有关连续曲线箱梁剪力滞系数的计算提供了参考依据。

In this paper , using spatial shell finite element method , the factors to shear lags effect of curvature's radius, wide span and other wide-body structure parameters on a continuous curved box bridge in the symmetric concentrated loads and uniformly distributed loads are analyzed .Compared with similar studies , the effect of shear lag on wide-body curves box bridge is more obvious .A calculation table of shear lag coefficient of four con-tinuous bridge across the wide-body is compiled in order to provide reference for the perfection of the existing standards of shear lag coefficient calculation for continuous curve box girder bridges .
