摘要

研究目的：蒙西至华中地区铁路通道工程浩勒报吉至三门峡段风沙、煤窑采空、黄土滑坡、崩塌等不良地质发育，同时沿线地貌类型复杂，沟壑纵横，大范围地面调绘工作开展困难。为优化地质调绘方法，提高不良地质勘察效率和质量，研究利用遥感判释技术进行沿线不良地质勘察。

研究结论：（1）研究采用高分辨率遥感和三维遥感技术相结合的方法，进行沿线不良地质遥感判释，查明了沿线不良地质分布特征；（2）划分出沿线毛乌苏沙漠区风沙分布特征，识别出煤窑采空分布范围，判释出270余处黄土滑坡和崩塌，判释准确率高于85%；（3）高分辨率遥感和三维遥感技术的综合应用可满足多类型不良地质勘察的需要，为地质选线提供了直接参考；（4）该研究成果可应用于艰险山区长大线路工程不良地质勘察工作。

Abstract：Abstract：Research purposes： The unfavorable geological conditions, like the drifting sand, coal pits, loess landslides and collapses, were developed at the Haolebaoji-Sanmenxia section of Mengxi-Huazhong railway. At the same time, the complex landform has made the big range geological mapping work more difficult than usual. In order to improve the survey quality and optimize engineering geological mapping work, the remote sensing interpretation technology was utilized for unfavorable geological condition survey along the railway.
Research conclusions：（1）Based on the high resolution and 3D remote sensing technology, we managed to find out the characteristics of the unfavorable geological condition distribution along the railroad.（2）The characteristics of the drifting sand and coal pits distribution along the railroad were studied, furthermore, more than 270 loess landslides and collapses were checked out with the accuracy rate above 85 percent.（3）The integrated application of the high resolution and 3D remote sensing technology have met the demanding of the multiple unfavorable geological conditions survey, which provided important basic data for the engineering geological alignment.（4）This study results can be applied in unfavorable geological condition survey of long route engineering, especially at rugged mountain ranges.
