Analysis of landslide deformation monitoring based on S-SAR
In order to improve the safety of open-pit mine slope and ensure the normal production of enterprises,it is the focus of research to strengthen the monitoring data analysis of slope surface deformation to obtain more accurate landslide time prediction.In this paper,the characteristic curve of slope surface deformation monitoring value in landslide is obtained by comparing and analyzing the radar deformation monitoring data of slope in two different mines,and then the relationship between deformation curve and landslide is judged.It is found that the slope will have several abnormal accelerated deformation phenomena before the destructive deformation,which is consistent with the three-stage deformation of Saito method.However,the slope will not only have one accelerated-uniform-re-accelerated deformation law before the landslide,but will repeat the deformation phenomenon of multiple accelerated-uniform-accelerated cycles.
