GPS monitoring on the representative landslides in Danba,Sichuan

The GPS monitoring has been made since 2006 for the deformation of the representative landslides in Danba,Sichuan,such as Jiaju,Ganqiaogou,Hongjunqiao and Yakaze landslides.According to the monitoring results,the displacement vector diagrams of individual landslides are generalized as follows.(1) Judged from the Jiaju landslide,the displacement of the northern side was bigger than that of the southern side during August 2006 to December 2007;(2) As the Ganqiaogou landslide is concerned,the displacement was relatively small during August 2006 to December 2007;(3) Compared with the deformation of the Hongjunqiao landslide,the deformation of the Yakaze landslide is more serious,with bigger displacement than the Hongjunqiao landslide.This research has important implications for the prediction and prevention of the landslides in Danba,Sichuan.
