遥感技术在库格铁路阿尔金山区地质选线中的应用

Application of Remote Sensing Technology in Engineering Geological Route Selection in Altun Mountain Area for Korla-Golmud Railway

阿尔金山地区山高坡陡、地质构造复杂、不良地质多且规模大,这些都为库尔勒至格尔木铁路地质选线带来较大的困难。因此,充分发挥遥感技术的优势,收集遥感图像及地形、地质图,进行遥感图像处理与提取地学信息,并相互叠加,根据图像反映的各类影像特征,综合野外调查,建立该区域的解译标志,开展中、大比例尺的遥感地质判释。综合应用遥感解译和地质调查手段,查明了测区地质构造和重大不良地质的分布特征,为大面积工程地质选线、优化线路方案提供了重要依据,为工程地质测绘勘探布置提供了指导性意见。

In Alton Mountain areas, there are many high mountains in the form of steep slopes, together with many complicated, unfavorable and large-scale geological structures, giving rise to great difficulty on engineering geological route selection for Korla-Golmud Railway. For this reason, remote sensing technology was employed in order to take full advantage of remote sensing technology. After collecting remote sensing images as well as topographical and geological maps, the remote sensing images were processed, the geo-science information was extracted, and the data were overlapped with each other. Furthermore, based on different image features, and comprehensively in combination with field survey, the interpretation marks of this region were established so as to do remote sensing geological interpretation in medium and large scale. As a result, by comprehensively using remote sensing interpretation and geological survey, the distribution pattern of geological structures and severely unfavorable geology in this region were ascertained. This practical application on infrared detection technology can provide an important basis for large-scale engineering geological route selection and for route scheme optimization, serving as guidance for arrangement of engineering geological mapping and surveying.
