摘要
利用遥感技术和高分辨的航空图像 ,对南昆铁路百色至米花岭路段及其两侧的斜坡变形等灾点开展遥感调查。在此基础上探讨斜坡变形灾点的成因 ,通过引进斜坡变形趋势评判数学模型 ,对斜坡变形灾点的稳定性进行预测 ,并对斜坡变形的灾点和路段进行评价 。
The high resolution air borne images and the remote sensing surveyare used to detect the disaster points from slope transformation (landslide,collapse,debris flow etc) in the section of Beise to Mihualing of Nanning Kunming Railway.The causes of disaster points from the slope transformation are discussed.The stability of disaster points from slope transformation is prediced with the mathematical model of trend judgment.The evaluation on the railway sectionand the protection measures against the harm of disaster points from slope transformation are provided.
