改建包兰铁路香山越岭段地质选线

Geological Route Selection in Xiangshan Crossing-mountain Areas of Rebuilt Baotou-Lanzhou Railway

改建包兰铁路香山隧道越岭地段工程地质条件复杂,通过各勘察阶段所采用的遥感判释、现场调绘、综合勘探等方法手段,对测区内工程地质条件进行详细分析,选取了具有优势地质条件的线路方案,减少了工程处理难度和后继隐患,增加了线路方案的可行性和可靠性。

The engineering geological conditions in Xiangshan crossing-mountain area of rebuilt Baotou-Lanzhou Railway are very complicated.With remote sensing,site surveying,integrative exploration and other engineering geological investigation methods in every reconnaissance stage,the engineering geological conditions in the surveying area are analysed in detail.Based on the analysis,the line scheme with better geological conditions is selected,which would reduce the difficulties in the construction and future troubles,and make the route scheme more feasible and reliable.
