摘　　要：向塘西编组站为路网性编组站。扩能改造工程需将既有混合式二级七场站型改扩建为纵向三级八场站型。因改建既有设备较多,对既有运营有较大的干扰。文章根据车流特点和运输生产需求,合理安排施工期间的车场和线路分配使用情况,详细分析了先实施上行系统、后实施下行系统并分场逐步实施的施工过渡方案。分析结果证明该扩能方案既可在有限的场地条件下满足运输生产的要求,又能确保设计方案顺利实施,避免了施工过渡便线,减少过渡工程。且在实施中贯穿了改建设计方案与施工过渡方案一体化设计的理念,对既有线大型车站设计方案与施工过渡方案的系统性设计具有很好的借鉴。Xiangtangxi marshalling station is a railway network marshalling station. Its capacity improvement project needs to make its existing two-stage-seven-yard into three-stage-eight-yard, where there are great many existing facilities to be improved and larger interference to the existing operation. Based on traffic flow characteristics and transportation demands, yard＇s reasonable arrangement during construction and track allocation and occupation, The detailed analysis has been made of the transitional plan for constructing the upgoing system firstly, then downgoing system and construc- ting the yard gradually and separately. The results has proved that such construction transitional plan can satisfy the re- quirements of transportation production in the restricted conditions of site, ensure the successful implementation of design plan, avoids the temporary line for building transition setcion, reduces transitional project, furthermore carry out the the- ory of integrating design and construction into one, and is a good example for other existing station design and construc- tion transitional plan.
