摘　　要：既有非电化铁路电气化扩能改造是当下中国铁路建设的重要方向。既有铁路桥上接触网悬挂安装设计是既有铁路电气化改造的重要一环,本文针对重庆枢纽既有朝阳嘉陵江大桥开展了接触网特殊悬挂安装研究,为国家重点建设项目节省了投资,缩短了建设工期。To electrify the existing non-electrified railway is a major trend for Chinese railway construction. Suspension and installation design of OCS （overhead contact system） on existing railway is a key link in electrification transformation for the project. In this paper, we studied a special suspension and installation mode for the existing Chaoyang Jialing River Bridge in Chongqing, which reduced the investment outlay and shortened the construction period.
