摘　　要：以某铁路工程项目中的公铁合建桥为例,对公铁合建桥接触网锚段布置进行研究,分析了大跨度钢索斜拉钢构桥梁端伸缩量偏大对接触网锚段布置的影响,提出了大跨度公铁合建桥中心锚结布置位置的建议方案及受梁端伸缩量影响导致的补偿坠砣升降空间不足的对应解决方案。This paper reports a case study on the layout of the contact network anchor section in the construction of an actual project of highway railway joint bridge.It analyzes the impact of excessive expansion and contraction at the beam end of a large-span steel cable cable-stayed steel structure bridge on the layout of the contact network anchor section,and proposes a solution for the central anchor arrangement position of the large-span highway railway joint bridge and the corresponding solution for the insufficient space for compensating the weight lifting caused by the expansion and contraction at the beam end.
