遥感技术在川藏铁路车站选址中的应用

川藏铁路拟选康定车站地处高山峡谷区,地形高差大,地质环境复杂,车站选址难度极大。为研究该铁路关键节点车站选址问题,本文充分运用高分辨率遥感技术,辅以热红外、InSAR等遥感新技术,对拟选车站选址区的活动断裂、不良地质等重大工程地质问题进行了详细判释和综合分析,遴选出三道桥设站为最优方案,可以为拟选车站选址及该段方案稳定提供重要依据,并指导工程地质调绘和勘探工作。结果表明:该方法效果良好,对于类似复杂艰险山区车站选址工作具有参考价值。

Application of remote sensing technology in site selection of a station on Sichuan-Tibet Railway

The Kangding station of Sichuan-Tibet Railway is located in the alpine valley area. It is extremely difficult to locate the station because of highly different terrain and complex geological environment. Through the full application of high-resolution remote sensing technology, supplemented by thermal infrared, InSAR and other new remote sensing technologies, the major engineering geological problems such as active faults and unfavorable geology in site selection area of the station are identified in detail and analyzed comprehensively. Sandaoqiao is selected as the optimum scheme for the station site. It provides an important basis and guidance for engineering geological mapping and exploration work. The research results have reference value for similar station location work in complex and dangerous mountainous areas.
