越岭地段铁路综合选线技术研究

Research on Comprehensive Route Selection Technology of Railway in Cross-Ridge Area

新建西宁至成都铁路位于青海、甘肃、四川三省交界地带,是我国“八纵八横”高速铁路纵向主通道兰(西)广通道的重要组成部分。新建正线长度496.67km,本线自北向南依次经西宁盆地区、拉脊山中高山区、华隆盆地区、西秦岭中高山区、若尔盖高原区、岷山中高山区六个地貌单元。本次对西秦岭越岭地段铁路综合选线技术进行研究,结合地形地貌、地质、站址选择、线路条件及工程投资等多方面因素对该区域线路方案进行综合比选推荐。

Xining-Chengdu Railway is located at the junction of Qinghai,Gansu and Sichuan provinces.It is an important part of Lan(West)Guangzhou Channel,the main longitudinal channel of the"Eight Longitudinal and Eight Horizontal"high-speed railway in China.The new main line is 496.67 km in length.From north to south,the line passes through six geomorphic units,namely,Xining Basin,Laji Mountains,Hualong Basin,West Qinling Mountains,Zoige Plateau and Minshan Mountains.This paper studies the comprehensive railway route selection technology in the cross-ridge area of the West Qinling Mountains,and makes a comprehensive comparison and recommendation of the railway route scheme in this area based on various factors such as topography,geology,site selection,line conditions and project investment.
