二级遥感技术在藏中联网工程中的应用

Application of Grade Ⅱ of Remote Sensing Technology in Transmission Line between Central Tibet and Changdu

遥感技术是一种运用现代化的运载工具和传感器,探测和识别远距离研究对象的技术。本文利用二级遥感技术对藏中联网500 k V线路工程全线地质灾害及塔基地质条件进行了研究,发现线路R335-R 337/L336-L338段为一古滑坡体,并经现场调查、勘察及定量评价,验证了遥感解译结果的准确性,为进一步在输电线路工程,尤其是山高坡陡的线路工程中推广遥感技术奠定了基础。

Remote sensing is a technology which uses modern delivery vehicles and sensors to detect and identify remote research objects. This paper has studied the geological disasters and geological conditions of tower foundations along the whole path way in the project of 500 kV electric transmission line between central Tibet and Changdu by using remote sensing technology, and found that the landforms from R335 to R337 and L336 to L338 on the line is an ancient landslide.Finally verified the accuracy of remote sensing interpretation results through field investigation, prospecting and quantitative evaluation, and laid a solid foundation in promoting remote sensing technology in projects of transmission line, especially in high mountain and steep slope areas.
