基于DEM的黑方台焦家滑坡变形分析
Deformation analysis of the Jiaojia landslide at Heifang platform based on DEM
摘要
Abstract
Taking the Jiaojia landslide in Yongjing, Gansu Province as the study object, a landslide deformation analysis model is established by ArcGIS using four periods of topographic maps obtained in 1977,1997, 2001, and 2010. Then a technical method of landslide deformation analysis is explored based on grid DEM. The calculation results show that retrograde eroding velocity of the landslide scarps is 4. 42 m/a between 1977 and 1997, 5.81 m/a between 1997 and 2001, and 1.64 m/a between 2001 and 2010.关键词
