摘　　要：山区电气化铁路受隧道净空和桥支柱安装位置局限性等因素的影响,桥隧相连段是接触网设计的难点和关键控制部位。就160 km/h以下客货共线铁路桥隧相连地段接触网设计的几个关键控制点进行分析和探讨,主要包括接触网支柱(悬挂点)的平面布置、导线高度和坡度的控制、锚段关节和中心锚结的位置选择、设备安装位置的选择、附加导线安装方式的选择等。Being restricted by some factors such as the tunnel clearance,positions of poles of overhead contact system(OCS) upon bridge and so on,the conjoint section of bridge and tunnel in electrified railway of mountain area is the difficult points and key points of OCS design.This paper analyzes and discusses several key control issues of OCS design of conjoint section of bridge and tunnel in mixed passenger and freight railway under 160 km/h,including mainly the layout plan of OCS poles(suspension points),the control of the height and slope of conductor,the selection of the overlap position,mid-point anchor position,equipment installation position,the installation ways of additive conductor,etc.
