四川丹巴县典型滑坡GPS监测效果研究
|
摘要
本文介绍了利用GPS监测丹巴县甲居滑坡、干桥沟滑坡、红军桥滑坡和亚喀则滑坡所获得的速度矢量图。监测结果表明:2006年8月~2007年12月甲居滑坡位移量北侧较南侧大,干桥沟滑坡位移量较小;2007年5月~12月红军桥滑坡位移量较小,亚喀则滑坡部分测站位移量较大,变形严重。
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.
