Abstract
In order to accurately grasp the formation mechanism of shallow bedding landslides and reasonably e-valuate their stability,the authors in this article first conduct an analysis of their formation mechanism based on the geological conditions of the landslide,and then use the transfer coefficient method and deformation prediction model to carry out the current situation evaluation and prediction evaluation of landslide stability.Example analy-sis showed that there were relatively many influencing factors for shallow bedding landslide,and they were easily affected by external disturbances due to the thin thickness of the sliding body of shallow landslide.Therefore,shallow bedding landslide was highly sensitive to various factors.In the evaluation results of landslide stability sta-tus quo,the stability coefficient under natural condition was 1.21,with stable status,the stability coefficient un-der rainstorm condition was 1.02,with unstable status.and the stability coefficient under earthquake condition was 1.09,with basically stable status.In the landslide stability prediction and evaluation results,the deformation prediction rates at each monitoring point of the landslide were higher than the existing deformation rates to some extent,indicating that the cumulative deformation of the landslide would continue to accelerate in the future.The results also indicate that the landslide stability tend to weaken after this monitoring period,and it is necessary to carry out landslide prevention and control research as soon as possible.The study results could provide certain theoretical guidance for the prevention and control of shallow bedding landslide disaster.关键词
