攀枝花至丽江160km/h单线铁路走向方案比选

攀枝花-丽江铁路位于四川省与云南省接壤地带,即四川省攀枝花地区、云南省丽江地区。线路自新成昆线攀枝花南站引出,折向西经华坪县、宁蒗县战河乡、永胜县至丽香线丽江站。复杂的地形地貌及地质影响跨金沙江桥位的确定,文章在详细分析金沙江沿江地形地貌及工程地质条件基础上,结合城市规划、工程投资及工程风险等因数对经战河永胜方案、沿金沙江右侧方案、经永胜方案、南线跨金沙江方案进行比选。通过比选认为,经战河永胜方案线路虽较长,但是兼顾宁蒗县站河乡,促进该地区发展,因此予以推荐。

Selection of Alignment Proposals of Panzhihua- Lijiang 160km/h Single Track Railway

Panzhihua - Lijiang railway is located in the border area of Sichuan province and Yunnan province, namely, Panzhihua area of Sichuan province and Lijiang area of Yunnan province. This railway line starts from the south station of the new Chengdu Kunming railway line and turns to west to arrive in Lijiang station of Lijiang Xianggelila railway line through Hua- ping county, Zhanhe township of Ninglang county and Yongsh- eng county. The location of the bridge across the Jiansha River cannot be confirmed easily due to the complex landforms and ge- ology. In this paper, basic on the analyses of the landforms and engineering geological conditions along the Jinsha River, four proposals are compared and selected with consideration of such factors as city planning, engineering investment and engineering risk. They are： proposal No. 1 ： through Zhanhe township and Yongsheng county; proposal No. 2： along the right side of the Jinsha River; proposal No. 3： through Yongsheng county; pro- posal No. 4： the south line crosses the Jinsha River. Through comparison, proposal No. 1 is recommended becausethe line goes through Zhanhe township of Ninglangcounty that can pro- mote the development of this area, though the line is longer in this proposal.
