摘　　要：六安—安庆铁路行经大别山东麓中低山构造区,越江淮分水岭,越岭隧道的选择是线路选线的重难点。文章结合越岭段地形地貌、不良地质情况,深入研究区域范围内的水利设施、断层分布、越岭高程、辅助坑道设置等边界条件,从线路平纵条件、桥隧工点设置、工程投资等方面出发,充分研判各项主要影响因素及其影响程度,按照“权衡利弊、避重就轻”的原则,对越岭隧道方案进行综合比选。The Lu'an-Anqing Railway passes through the middle and low mountain tectonic area in the eastern foot of the Dabie Mountains,and crosses the Jianghuai watershed.The selection of the ridge crossing tunnel is the key and difficult point of the route selection.Based on the topography and unfavorable geological conditions of the ridge crossing section,this paper deeply studies the boundary conditions such as water conservancy facilities,fault distribution,ridge crossing elevation and auxiliary tunnel setting in the area.Starting from the horizontal and vertical conditions of the route,the setting of bridge and tunnel construction sites,engineering investment and other aspects,it fully studies and judges the main influencing factors and their influence degree.According to the principle of"weighing the pros and cons,beating around the bush",the ridge crossing tunnel scheme is comprehensively compared and selected.
