摘　　要：向塘西编组站位于京九、沪昆两大铁路通道的十字交汇点,路网性编组站之一。受历史条件制约,下行系统为混合式二级三场站型,上行系统为横列式一级三场+直通场的站型。经济的迅速增长,既有站型和各车场的规模远不能满足运量的快速增长,严重制约了路网货物的周转。文章通过深入分析,从改扩建的必要性、影响因素分析、设计思路、综合方案确定等多个角度对改扩建方案做了系统阐述。针对上行系统提出了新建上行到达场(站型改为混合式二级四场+直通场站型)、改扩建调车场和出发场的方案;针对下行系统提出增设下行出发场(站型改为纵列式三级三场)、大规模扩建调车场的方案,消除了横列式站型转场控制解体能力、混合式二级三场站型制约解编能力的问题。成功将既有混合式二级七场改建为双向纵列式三级八场站型,从而满足近、远期运能的需要。Xiangtangxi marshalling yard is one of the major national network marshalling yards in China.It is located at the intersection of the Jing-Jiu railway and Hu-Kun railway.Restricted by historical conditions,the layout of down sys-tem is hybrid secondary three yards and up system is transversal one-level three yards plus through yard.With the rapid development of our economy,the layout of existing station and the scale of the yards are not sufficient to meet the sub-stantial capacity growth and severely restricted the turnover of railway network.Through in-depth analysis,we made e-laborate system study on the station reconstruction and expansion from multiple angles such as the necessity,influence factor analysis,design idea,comprehensive scheme determination etc.For the up system the paper proposed the scheme of new upward arriving yard and reconstruction and expansion of switchyard and departure yard.For the down system we proposed the scheme of new downward departure yard and large-scale reconstruction and expansion of switchyard,thus eliminating the problem of constraints on the disassembly capacity of transversal layout transit and constraints on the sor-ting capacity of hybrid secondary three yards.The scheme successfully converted the hybrid secondary seven yards into bidirectional parallel third eight yards and so met the needs of short-term and long-term transport capacity.
