| 摘 要： | 针对曲梁桥常出现的横向偏移现象,以某独墩单支座的曲线连续钢箱梁桥工程实例,采用通用有限元软件进行了仿真分析,针对曲梁桥的特点,采用竖向顶升和横向顶推相结合的复位方法,优化了顶推复位工序,确定了每点的顶(推)力计算方法.施工实践及运营情况表明,该复位方案合理、可靠.

| Abstract: | The creep deformations of curved girder bridge often occur.This paper makes a deviation rectifying research on lateral and torsional distortion of simple-supported continuous curved steel box girder bridge.By using FEM software MIDAS,the combined construction scheme of vertical and lateral thrusting is determined to rectify the curved beam.The construction process is optimized according to the characteristic of curved beam.Respectively methods are presented to caculate the thrusting force.The construction scheme is proved to be reasonable and practical in the practice. |
