摘要
铁路建设对城市发展具有较大带动作用,但我国首批建设的铁路客站已基本被城市建(构)筑物包围,导致新建铁路引入既有客站难度极大。为解决广州铁路枢纽广州站和佛山站只有单线连接,通道能力紧张,位于中心城区的广州站和佛山站仅能承担普速客运、货运和少量动车作业等问题,采用普速客车和普速货车外绕、利用既有铁路打通东西向四线高铁通道、高铁直接引入中心城区3项措施,从根本上优化广州枢纽格局,据此广茂铁路客运需调整至经广珠京广联络线引入白云站。结合行车检算、限制坡度、机车类型等因素研究比选双线和单线共4个广珠京广联络线方案,从线路长度、工程投资、运营维护条件、能力适应性、在建铁路影响等方面进行综合研究,比选后推荐单线20‰坡度方案。研究成果可为类似铁路枢纽(地区)引入线路的设计提供借鉴和参考。
Railway construction has a significant impact on urban development,but the first batch of railway passenger stations and railway lines constructed in China are now mostly surrounded by urban buildings,making it extremely difficult for newly built railways to introduce existing passenger stations.The Guangzhou Zhanjiang High-speed Railway has fundamentally optimized the layout of Guangzhous hub by adopting three major technological innovations:conventional passenger trains and freight trains bypassing,opening up the east-west four line high-speed rail corridor,and introducing high-speed rail directly into the central urban area.Based on this,the passenger transportation of Guangzhou-Maoming Railway needs to be adjusted to the introduction of Baiyun Station on the Guangzhou-Zhuhai Railway to Beijing-Guangzhou connecting line.The following text combines factors such as train operation calculation,limited slope,and locomotive type to study and compare four schemes in two series:double track and single track.After comprehensive research and comparison,a single track 20‰slope scheme is recommended.The results could be used as references for future design of connection lines introducing into railway hubs.
