| 摘 要： | 以淮北相王大桥为背景，对大斜度桥梁斜塔钢构爬模进行刚度仿真分析和结构优化。通过建立钢构爬模有限元模型，并导入 Workbench14.5进行仿真分析，得出爬模危险应力集中区域及最大变形量位置。并对下侧立面爬模结构进行优化，优化后爬模整体应力分布均匀，最大应力减少约30%，保证了爬模的刚度，控制模板的变形量。为大斜度桥梁斜塔钢构爬模设计提供了参考。

| Abstract: | Combined the construction project of Huaibei Xiangwang Bridge, the stiffness simulation and structural optimizing of steel climbing form used in the large slope bridge tower are done. Through establishing the mode of climbing form, impor-ting the mode to the Workbench14. 5 proceeding simulation analysis to get the dangerous stress concentration area and maxi-mum deformation position of climbing form. Then the structure of downside surface climbing form is optimized. The stress of downside climbing form after optimization is uniform and maximum stress is reduced about 30% , which ensures the stiffness and control the deformation of the template. The reference is provided to the design of the climbing form used in the large slope bridge tower. |
