摘要:
 为明确前支点挂篮施工斜拉桥施工过程中挂篮变形及受力状态，针对影响施工控制精度的节段施工中间张拉过程与前支点挂篮密切相关的问题，基于前支点挂篮受力分析及MIDAS CIVIL有限元模拟，提出了中间张拉索力计算公式及挂篮参与整体受力及变形的9步施工过程模拟分析方法，并与实际工程中结构受力状态和变形状态进行了对比分析.结果表明，根据这种施工过程模拟分析得到的施工预拱度、中间张拉过程理论高程及内力状态满足施工控制精度的要求，可用于指导实际工程.
Abstract:
 In order to determinate the deformation and stress state of travelers in the construction stage of cable-stayed bridges constructed by fore fulcra form travelers, and consider the fact that the tensioning process in the construction stage, which influences the construction control precision, is closely related to the fore fulcra form travelers, we put forward the formula of the cable forces together with nine steps of construction simulation analysis method based on mechanical analysis and finite element analysis with MIDAS CIVIL of fore fulcra form travelers． We consider the travelers bear force and deform as a part of the whole structure, and then compare the stress state and deformation state in the model to those in practical engineering. The results show that the construction camber, theoretical evaluation and internal force state in tensioning process obtained by this construction simulation analysis method meet the accuracy requirement in construction control. The method can be used to guide practical engineering.
