Failure mode and deformation characteristics of open-air bedding soft rock slope based on S-SAR
The deformation of open-air bedding soft rock slope is creep for a long time,and the failure is often difficult to predict and check in advance.In order to explore the deformation characteristics before and after failure and improve the accuracy of landslide warning,the failure mode of open-pit strata soft rock slope was analyzed based on a lead-zinc mine in Xinjiang,and the deformation characteristics before and after the slope step failure were obtained based on the slope synthetic aperture radar(S-SAR)field monitoring data.The results show that the failure modes of open-pit bedding soft rock slope are mostly collapse and flow caused by self-weight and strong weathering,and the failure occurs in the accelerated deformation stage of slope,and the overall time of slope deformation and displacement in the three stages is about 7d.At the same time,combining radar monitoring data provides a reasonable suggestion for mine online monitoring and early warning,and can provide a reference for the safety production of open-pit mine under similar conditions.
