摘　　要：交叉渡线道岔是由四组辙叉号相同的单开道岔和一组菱形交叉组成,主要功能是缩短站场长度,减少占地面积,因而在铁路上得到广泛的应用。在既有铁路改造换岔过程中,结合现场实际,通过方案优化,更加高效、快捷、安全、正点地完成了施工任务,减少了施工对既有铁路运输的影响,为类似工程提供了借鉴经验。The crossing crossover turnout is composed of four groups of single turnout with the same frog number and a group of diamond crossings.Its main function is to shorten the length of the station yard and reduce the floor area,so it is widely used in the railway.In the process of existing railway transformation and switch changing,combined with the actual situation on site,the construction task was completed more efficiently,quickly,safely and on schedule through scheme optimization,which reduced the impact of construction on existing railway transportation and provided reference experience for similar projects.
