遥感技术在公路工可研阶段工程地质调绘中的应用

阐述了遥感技术工作原理、手段、方法及发展现状，通过目前在内蒙古自治区两项重点公路工程工可研阶段工程地质调绘项目中的应用，介绍了利用遥感技术进行地质选线、地质判译，并结合现场踏勘调查，较准确的掌握走廊带区域工程地质、工程地质条件及河流水系、地形地貌特征等情况．有针对性地对圈出的不良地质区域进行地质勘察工作，从而提高了方案的准确性、可比性及工可研阶段的工作效率，缩短了外业工作周期、降低了成本，显示出遥感技术在公路工可研阶段工程地质调绘中起到的重要作用。

Application of remote sensing to engineering geological condition investigation at the stage of feasibility study for a project

The working principle, the means, the methods and the developing situations of the remote sensing are described in this article, in accordance with application of this technique to two major projects in Inner Mongolia Autonomous Region at the stage of feasibility study. This article presents the geological selection of route, the geological condltion.judgment by using of remote sensing technique, thus knowing well in more precise term, in combination with the reconnaissance survey, the geological conditions, river system, the terrain and its features, etc., in the poor geological zones localized. The geological investigation is carried out to improve the accuracy of the project, the comparability, the working efficiency at the stage of feasibility study, and reduce the cycle of field working and the cost. It has been proven that remote sensing can plays the important role in geological investigation for highway project.
