成自铁路引入天府机场线路方案比选回顾

Review of Comparison and Selection of Route Plans for the Connection of the Chengdu-Zigong High-speed Railway to Tianfu Airport

成自铁路作为国内首条350km/h下穿机场的高速铁路,如何实现高速铁路航空的一体化发展和机场综合换乘中心各种交通方式的无缝衔接值得深入研究。本文结合天府机场近远期、地铁、铁路、道路和综合管网等规划,首先确定了铁路的纵断面方案,然后针对平行机场跑道、斜穿机场、正穿机场3个线路方案,从工程投资、方便旅客出行、与机场规划结合等方面综合比选,最终确定采用能更好的满足人民群众高品质的出行需求的斜穿机场方案。研究成果可为类似项目提供借鉴。

As the first 350 km/h high-speed railway passing through an airport underground in China,how to realize the integrated development of high-speed railway and aviation and the seamless connection of various modes of transportation in the airport comprehensive transfer center is worth in-depth research. Combined with the short-term and long-term planning of Tianfu Airport,metro,railway,road,and integrated pipe network,this paper first determines the longitudinal section plan of the railway,and then comprehensively compares the three route plans,namely running parallel to the airport runway,crossing airport with an oblique angle,and crossing airport with a right angle from the aspects of project investment,convenient travel of passengers and combination with airport planning,and finally determines the plan of crossing airport with an oblique angle can better meet the high-quality travel needs of the people.The research results can provide references for similar projects.
