焉耆盆地段高速公路遥感选线应用研究

Research on Application of Select Route with Remote Sensing in Yanqi Basin Section of Expressway

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Landsat－5 TM457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，在此基础上比较各设计线路之划分亚区，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，并提出科学合理的建议线路方案。

In the earlier research of select route on Yanqi Basin Section expressway of No.314 State highway, Landsat－5 TM457 digital image was main informational source. Get through digital processing and remote sensing interpretation and comprehensive analyses of conventional informations, further divided the soil engineering geological region of Quaternary alluvial plain into sub－areas, and analysed the distributive law and formative background and grow trend of harmful geological phenomenons. On this basis, comparison between the merits and demerits of different design routes, and provide rational suggestions of route scheme.
