斜拉桥锚固结构细部分析与优化

Detail Analysis and Optimization of Anchorage Structure of Cable-stayed Bridge

斜拉桥是一种自锚式体系,斜拉索的水平力由梁承受,拉索连接了主塔与主梁,作用于锚固结构。而锚固结构的受力大、构造复杂,对材料及构造设计的要求很高。笔者通过对某斜拉桥锚固结构的仿真计算,展示了此类构造的分析过程与优化原理,为同类项目提供可参考的案例及依据。

Cable stayed bridge belongs to self anchored system.The horizonal force of stay cable is bored by beams.The cables act on the anchorage structure by connecting the main tower and main beams.The anchorage structure has large stress and complex structure,and has high requirements for material and structural design.Through simulation calculation of the anchorage structure of a cable-stayed bridge,the analysis process and optimization principle are show.It provides a reference case and basis for similar projects.
