国道314线焉耆盆地段高速公路遥感选线应用研究

The application of remote sensing technique in the national highway of GD 314 Yanqi basin area

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。在国道 314线焉耆盆地段高速公路前期选线研究中 ,以 L andsat- 5 TM45 7数字图象为主要信息源 ,通过数据处理和遥感判释并综合分析常规资料 ,对焉耆盆地段第四纪堆积平原土体工程地质区进一步划分亚区 ,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 。

Remote sensing technology shows its uncompetative advantage on national highway selection during the comparing and selecting of GD314 in the Yanqi Basin region.By using Landsat\|5 TM457 multichannel spectra reflectivity remote sensing data,through digital imagery data processing and general data analyzing,this paper classified engineering geological subregion in Yanqi basin area.Then the paper discussed and analyzed the distribution regularity,background and development trend of natural geological disasters.On the basis of above all,the author compared the engineering condition of different lines and finally put forward the reasonable line.
