公路工程地质遥感勘察

THE REMOTE SENSING OF HIGHWAY ENGINEERING GEOLOGY

卫星遥感技术应用在公路选线中 ,具有常规方法无可比拟的优势。在湖南省常德 吉首高速公路初勘研究中 ,以正射航空相片、Landsat TM数字图像为主要信息源 ,通过数据处理和地学遥感判释 ,并综合分析其它资料 ,对常吉公路沿线地区进行了地质构造、地层、地貌、地表水、第四系等遥感专题调查 ,探讨分析了不良地质现象分布规律、形成背景及发展演化趋势 ,在此基础上比较各设计线路之优缺点 ,并提出科学合理的建议线路方案。方法对自然条件十分复杂的西部公路建设有较好的借鉴意义。

In the preliminary exploration of Changed Jishou experssway in Hunan Province,the remote sensing investigation of geologicalphy structure,strtatigraphy,geomorphology,surface water and quaternary of the expressway area has been carried out according to the data process and geological interpretation of aerial orthophoto,Landsat TM digital image as main information origin and the comprehensive analysis of other materials.And the distribution,formation background and evolution trend of disadvantageous geological conditions are discussed and analyzed.On the basis of comparison of varous design schemes,the tational route is proposed.
