关于深圳都市圈城际铁路选线设计思路的探讨

Research on the Route Selection Design of Intercity Railway in Shenzhen Metropolitan Area

研究目的:通过对粤港澳大湾区城际铁路分布差异性分析,新时代都市圈城际铁路呈现引入城市中心的发展趋势;对于穿行城市中心的城际铁路,因受城市规划、交通、水利、环保、建(构)筑物等诸多外部因素控制,为了实现城市与城际铁路协同发展,确保项目顺利建设,对穿越城市中心的城际铁路选线设计思路进行系统梳理和研究。研究结论:(1)在总体选线方面,对规划符合性、环境保护等方面提出了建议;(2)在车站分布及选址方面,对站间距及站位选择进行了分析并提出了车站设置思路;(3)在线路引入车站、机场方面,对引入的线路方案提供了设计思路;(4)在区间选线方面,结合沿线地形、地质情况、外部建(构)筑物等控制因素,对线路平、纵断面设计提出了建议;(5)本研究成果充分结合了深圳都市圈城际铁路建设经验,对新时期城际铁路平、纵断面设计及线站位方案稳定具有指导和借鉴意义。

Research purposes:Through the analysis of the difference in the distribution of the inter-city railway in Guangdong-Hong Kong-Macao Greater Bay Area,the inter-city railway in the new era metropolitan area presents the development trend of introducing the urban center.For intercity railways passing through the urban center,due to various external factors such as city planning,transportation,water conservancy,environmental protection,and structures,in order to achieve coordinated development between the city and intercity railways and ensure smooth construction of the project,a systematic review and research have been conducted on the design ideas for the route selection of intercity railways passing through the urban center.Research conclusions:(1)Suggestions were put forward for overall route selection,including planning compliance and environmental protection.(2)From the perspective of station distribution and location selection,the spacing and location selection of stations were analyzed,and thought for station setting was proposed.(3)The design ideas for the introduced route scheme from the perspective of introducing stations and airports were provided.(4)From the perspective of interval route selection,combined with control factors such as terrain,geological conditions,and external structures along the railway,suggestions were put forward for horizontal and vertical design.(5)The research results fully combine the construction experience of Shenzhen metropolitan area intercity railway,and have important guidance and reference significance for the horizontal and vertical design of intercity railway,and the stability of route and station scheme in the new era.
