摘　　要：利用SAP通用有限元分析软件 ,采用三维板壳单元模拟连续曲梁及横隔板 ,用实体单元摸拟桥墩 ,三维梁单元模拟扇形吊杆及直线拱肋 ,对一曲线连续箱梁斜腿刚构系杆拱组合体系桥进行三维分析 ,连续弯箱梁剪力滞现象比较突出 。This paper makes three dimensional analysis to the shear lag effects of the construction of the combination bridge with curved continuous rigid frame structure and tied arch bridge, based on SAP finite element common software. And three dimensional shell elements simulate the curved beam and horizontal partition, solid elements simulate bridge pier and three dimensional frame elements simulate fan-shaped boom and rectilinear arched girder. The analysis also shows, shear lag effects of box girder is rather distinct ,which should be seriously taken by engineers.
