赤大白铁路巴彦段增建二线线路方案研究

Research on the Second Line Construction Project of Chifeng-DabanBaiyinhua Railway Bayan Section

赤大白铁路巴彦段既有线为R=600 m的回头曲线,在该线扩能工程的研究过程中,本段的增建二线方案影响到线路主要技术标准的选择。从线路方案研究的总体思路出发,综合线位对移民新村的影响和工程投资、水害治理、线路纵坡的选择等多种因素,对R=600 m、R=700 m、R=800 m的方案进行了综合比选。

Bayan section lines of Chifeng-Daban-Baiyinhua railway is a back curve of R =600 m.In the study on the capaci-ty expansion,it is found that the selection of second line scheme has great impact on the main technical standards of the rail-way.In this paper,from the general idea of the route,a comprehensive comparison and selection of R =600 m,R =700 m, R =800 m solutions is made from perspectives of the comprehensive effects of various factors on immigrants and project in-vestment,water treatment,the choice of longitudinal slope.
