珠海至肇庆高速铁路引入珠海枢纽方案研究

Research on the Scheme of Introducing of Zhuhai-Zhaoqing High-speed Railway into Zhuhai Railway Hub

为确定珠肇高铁引入珠海枢纽的最优方案,对珠肇高铁的功能地位、珠海铁路枢纽内既有铁路现状、枢纽总图格局、城市总体规划、枢纽内客运作业量和车流特点等多重因素进行分析,得出枢纽内既有和在建车站均无法满足新线的引入要求,亟需另行择址新建枢纽客运站,故将珠肇高铁及规划线路引入新建珠海鹤洲站。采用综合经济技术比选的方法,分析比较各方案线路条件、对城市规划的影响、工程投资、工程实施难度等,分别系统研究香海高速以南、江珠高速以西站址方案,香海高速以北、江珠高速以西站址方案,香海高速以北、紧邻江珠高速站址方案以及香海高速以北、江珠高速以东站址方案等4个方案。研究表明,鹤洲岛香海高速以南、江珠高速以西设站方案线路顺直,引入条件好;车站与动车所的综合布置更加合理且与城市规划结合较好;工程实施难度小,工程投资最省,故予以推荐。

In order to determine the optimal scheme for the introduction of Zhuhai-Zhaoqing High-speed Railway into Zhuhai Railway Hub,the paper analyzed the functional status of Zhuhai-Zhaoqing High-speed Railway,the current situation of existing railways in Zhuhai Railway Hub,the general layout of the hub,the overall urban planning,the passenger operation volume and traffic flow characteristics in the hub.It is concluded that the existing and under-construction stations in the hub cannot meet the requirements of the introduction of new lines.It is urgent to build a new hub passenger station at a different location,and introduce Zhuhai-Zhaoqing High-speed Railway and planned lines into the new Zhuhai Hezhou Station.In this paper,through the investigation of the Hezhou Island topography,using the method of comprehensive economic and technical comparison and selection,the route conditions of each scheme,including the impact on urban planning,project investment,project implementation difficulty,were studied respectively.Location schemes including the south of Xianghai highway,the west of Jiangzhu highway,Xianghai highway to the north,Jiangzhu highway to the west,Xianghai Highway to the north,adjacent to Jiangzhu Highway and Xianghai Highway to the north,Jiangzhu Highway to the east,were analyzed.The research shows that,the scheme of setting up stations in the south of Xianghai Expressway and the west of Jiangzhu Expressway on Hezhou Island has straight alignment and better introduction conditions.The comprehensive layout of the station and the EMU station is more reasonable and better integrated with urban planning;the implementation of the project is less difficult and the project investment is the most economical,so it is recommended.
