摘要：
Landslides cause great harms to transmission line corridor in mountainous area. This paper uses a method of identifying landslides to evaluate harmfulness to power towers. First, the mountainous area is classified as nine categories in terms of polarimetric decomposition techniques and clustering algorithm. Second, landslides are detected based on the change of areas before and after a landslide with respect to classification categories. Third, landslide hazard to power towers is given in terms of geographic coordinate and pixel resolution. Finally, experiments over Zhaojue county and Mao county were carried out and the discussions for the two transmission line corridors in these two study areas were given.
