摘　　要：乐化站位于南昌枢纽北端,为既有京九铁路上的一个中间站。随着南昌枢纽格局的调整,规划建设昌九城际铁路、南昌枢纽西环线、向莆铁路、沪昆客运专线引入南昌枢纽,形成了以乐化为轴心的乐化客货疏解区。文章通过乐化疏解区的形成、衔接铁路的项目特点、各工程实施进度节点,详细分析介绍了枢纽西环线提前开通的乐化疏解区施工过渡设计方案,根据枢纽内运输组织特点,巧妙利用了正线与站线简易换边的技术手段,在维持既有京九铁路运输方式不改动的情况下,提前单线接通西环铁路,缓解一定时期内枢纽客货运输能力紧张,以较小的代价,创造了较高的经济效益和社会效益。As an intermediate station of Beijing-Kowloon Railway, Lehua station is located at the north of Nanchang ter- minal. With the layout adjustment of Nanchang terminal, and Changjiu intercity railway, west loop line of Nanchang ter- minal, Xiangpu railway and Shanghai-Kunming passenger dedicated line led into Nanchang terminal, Lehua passenger and freight untwining zone is formed. By introducing the forming of Lehua untwining zone, the project characteristics of connecting railways and projects implementation progress nodes, this paper analyzes the transitional construction scheme of Lehua untwining zone being open to traffic in advance of terminal west loop line. According to the transportation or- ganization characteristics in terminal, taking advantage of the technical means of simplified line and station line and maintaining the transportation mode of Beijing-Kowloon railway through in advance with single line, which reduces the intense passenger and freight transpo changing side between main , the west loop line is put rt capacity in a certain peri-od in terminal and creates higher economic and social benefits with less cost.
