摘　　要：大型枢纽高架站一般站场规模较大,对于信号专业而言,室外信号设备多且信号电缆数量巨大。高架站上信号电缆敷设条件比地面站更为苛刻,桥上电缆槽及过轨设置条件有限。由于设计阶段未对整个站场电缆分布及过轨进行合理规划,且站前和站后专业接口分工尚无具体规范可依,导致后期施工无条件过轨,而采取其他临时补救措施又造成后期施工困难、设备接管单位维护不便、工程造价提高等。本文研究大型高架车站信号电缆过轨方法,并结合桥梁及轨道型式、电缆数量提出针对性过轨方案,以期对后续项目建设提供指导。As the signal specialty,there are more outdoor signal equipment and a huge number of signal cables on large hub elevated stations.The laying conditions of the signal cable on elevated station are more severe than on the ground station,and the conditions of setting the cable channel and the crossing rail on the bridge are limited.Because there is no a reasonable planning for the cable distribution and cable crossing of the whole station in the design stage,and there is no specific norms to follow on interface between station and signal,leading to post-construction unconditional rail crossing,while the adoption of other temporary remedial measures will cause difficulties for post-construction,inconvenience in the maintenance of the equipment take-over units,and increase in the project cost.In this paper,the signal cable cross-rail program of large overhead station is studied,and a targeted cross-rail scheme is proposed considering the bridge and track type and the number of cables,hoping to provide guidance for the construction of the latter part of the project.
