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.

Key words： Key words: high resolution remote sensing 3D remote sensing drifting sand; loess landslide collapse; remote sensing interpretation
