为了确定支座维修处置的效果,确认桥面板顶推复位的准确性,本文采用了非线性分析软件ABAQUS建立全幅桥面板壳单元三维实体分析模型,对顶升时桥面板局部应力进行了详细的分析;采用此种仿真分析桥面局部顶升,确保了更换支座操作过程的结构安全性。也为其他桥梁支座更换时桥梁面板的局部顶升提供参考和施工依据。
In order to confirm the effect of bearing repairing and dismantling, and to confirm the accuracy of thrust reduction of bridge deck, a three-dimensional solid analysis model of full-deck bridge deck shell element was established by using non-linear analysis software ABAQUS. Local stress of bridge deck was detailed Analysis; the use of such simulation analysis of the local rise of the bridge to ensure the replacement of the pedestal during the operation of the structural safety. It also provides reference and construction basis for the local lifting of bridge panels during the replacement of other bridge supports.
