中文摘要:
      准确的施工过程仿真计算与分析是大跨度混凝土斜拉桥施工监控的关键问题之一,它可以为大桥各阶段的施工控制工作提供理论指导。根据涡河三桥主梁施工工艺和结构特点,分别建立牵索挂篮悬浇施工的前支点和后支点有限元计算模型,分析并对比了主梁的截面内力及线型的变化规律,从而为大跨柔性斜拉桥的施工控制提供理论依据
英文摘要:
      The accurate construction process simulation and analysis is one of the key issues in the con- struction control of long-span concrete cable-stayed bridges, It can provide a theoretical guidance for the control of each stage in the bridge construction. According to the construction characteristics of the main girder of Guo-River Bridge, two finite element models of construction process with the front fulcrum and the rear fulcrum Guyed Travelers are established, the internal force of the main girder and linear changes are compared, so the construction control of the bridge can acquire theoretical foundations.
