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 conclusions：This paper introduces the main design principle and technical standards for construction of Guangzhou-Qingyuan Intercity Rail Transit, compares and analyzes the three schemes in economy and technology from the fields of construction cost, construction difficulty, construction schedule, environment protection and coordination with the city planning, on the premise of meeting the track alignment, and offers the optimal scheme on the track alignment in city, namely, the scheme of track along Jingfu Road. This scheme can be as the reference to construction of the similar intercity rail transit.
