摘要
研究目的:随着我国铁路建设重心向中西部转移,艰险山区铁路明显增多。针对某山区铁路工程地质勘察需求,研究采用多光谱遥感、热红外遥感、雷达遥感、高分辨率遥感和三维遥感相结合的综合判释方法,开展沿线断层、高地温、滑坡、崩塌、泥石流、不稳定斜坡、岩屑坡、冰川融蚀等地质问题的解译工作。研究结论:(1)利用多光谱遥感、雷达遥感相结合的方法,解译沿线断层500余条,基本查明了构造分布特征;利用高分三维遥感技术,解译各类不良地质150余处,为重要工点方案比选提供了参考;(2)分析了该线断层、崩塌、滑坡、泥石流等不良地质,以及冰川融蚀、岩屑坡等冰缘地貌的遥感解译标志特征,并提出了需要进一步开展的遥感工作内容;(3)本研究成果可应用于艰险山区铁路工程地质勘察及设计选线。
Research purposes:Along with the fast railway construction in the western regions,the number of difficult mountain railways had increased significantly in the past years.In order to improve the survey quality and optimize engineering geological investigation work in a mountain railway,multi-spectral remote sensing,thermal infrared remote sensing,radar remote sensing,high resolution remote sensing and three-dimensional remote sensing techniques were utilized to interpret the unfavorable geological conditions,such as faults,high ground temperature,landslides,collapses,debris flows,unstable slopes,debris slopes and glacier erosion.Research conclusions:(1)Based on the multispectral and radar remote sensing technology,more than 500 faults were checked out and the distribution characteristics of the faults have been basically identified;Based on the high resolution 3D remote sensing technology,more than 150 unfavorable geologies were interpreted,which provided a reference for the scheme comparison.(2)The remote sensing interpretation keys of the unfavorable geologies were introduced,as well as the contents of in-depth remote sensing work were discussed.(3)The research result can be used for engineering geology investigation and alignment of mountain railways.
