摘　　要：建立了应用平面杆系有限元法计算程序分析连续弯箱梁桥的计算模型 ,并且还引入了应力增大系数来计入约束扭转产生的效应。本近似分析法可以给出较高精度的计算结果 ,因此 。The calculating model for analysis of continuous curved box girder bridges by plan element computer program is established. The increasing coefficient of section stress accounted to the effect of restrain torsion is introduced. This approximate method may give the calculation results with higher precision.Therefore, it has practical significance for disigners.
