研究目的:以广州至清远城际轨道交通线为例,就在清远市的线路走向方案进行研究,通过对3种方案经济技术条件的比较,提出可行性方案。为珠江三角洲的城际轨道交通发展奠定基础。研究结论:针对广州至清远城际轨道交通线,阐述了主要设计原则和技术标准,在满足线路走向的前提下,从工程投资、施工难度及工期、环境保护及与城市规划的配合等方面,对3种方案进行了经济技术比较与分析,提出了城际轨道交通线路经由城市时的最优方案(沿静福路方案)。该技术方案的研究可为其它城市间城际轨道交通线路的建设提供借鉴。
Research purposes: Taking the Guangzhou-Qingyuan inter-city rail transit line as an example, this paper studies the line-oriented scheme in Qingyuan City and puts forward a feasible scheme by comparing the economic and technological conditions of the three schemes. Laying the foundation for the inter-city rail transit development in the Pearl River Delta. Conclusions: According to the intercity rail transit line from Guangzhou to Qingyuan, the main design principles and technical standards are elaborated. Under the premise of meeting the line direction, from the aspects of project investment, construction difficulty and duration, environmental protection and urban planning, Economic and technical comparison and analysis of the three schemes were made, and the optimal scheme of intercity rail transit line passing the city was proposed (along the Jingfu Road scheme). The study of this technical scheme can provide references for the construction of intercity rail transit lines in other cities.
