摘　　要：道岔上方的接触网结构较复杂,是维修维护需要重点关注的区域。本文针对某地铁线路9号道岔上方接触网出现的受电弓弓角异常磨损、接触线侧面异常磨损等问题,从受电弓、接触网空间几何关系出发,分析了造成线岔区域异常磨损的原因,给出了线岔布置的原则和线岔结构的调整方案建议,为城市轨道交通9号道岔上方接触网布置提供参考。The structure of contact line over track point area which is more complex,attracts more maintenance attentions.There are some faults related to overhead contact line system over 9#track points in urban rail transit,such as abnormal wear on the pantograph bow angle and contact wire.Based on the geometry parameters of pantograph and overhead contact line system,the reasons for the faults are analyzed.So the paper gives some suggestions about the arrangement principle and the adjustment programs of the intersecting point wiring which is benefit for the design of overhead contact line system over 9#track points in urban rail transit.
