Landslides early warning application based on improved tangent angle method in Open-pit Mines
LI Qianhui
Abstract：In order to realize the monitoring and early warning of landslide disaster effectively,avoid and reduce the threat and loss caused by disaster,based on the improved tangent angle model of three-stage creep theory,the article studies change law of tangent angle in the dynamic development of landslide,combines with the application analysis of landslide cases,successfully realizes the stage early warning of landslide.The results show that the improved tangent angle method can effectively distinguish the different acceleration stages in the process of landslide acceleration deformation and identify the acceleration trend.The improved tangent angle method combined with velocity reciprocal and slope landslide time prediction method can effectively realize early warning and forecast,which provides data support for taking early warning measures in time.
