摘要
渝昆高速铁路会泽至蒲草塘段地质条件复杂,自然保护区遍布,是渝昆高速铁路的建设难点。在阐述渝昆高速铁路会泽至蒲草塘段线路概况的基础上,从工程地质、环境敏感区影响、工程投资、工程实施难易程度及工程可实施性5个方面对线路走向进行研究,确定待补东绕方案为最佳线路走向方案。从调整线路平面和纵断面2个方面进行坡度软化方案比选,对坡末速度进行分析,合理确定渝昆高速铁路会泽至蒲草塘段线路走向及坡度方案,为渝昆高速铁路全线早日接入我国高速铁路网络奠定基础。
With complex geological conditions and many natural reserves, Huize-Pucaotang section of Chongqing-Kunming High-Speed Railway is one of the critical parts of the project. In this paper, we first elaborate the situation of this section and studies the alignment from 5 aspects: engineering geology, environmental sensitive areas, investment, engineering difficulty level, and feasibility. The best alignment is the Daibu town east circle line plan. The plane and profile layout of the alignment are compared, and the gradient end speed is analyzed to define the gradient. Finally, we propose the alignment and gradient of the section. This will lay the foundation for ChongqingKunming High-speed Railway to the national network.
