Evaluation of Landslide Stability Development Trends Based on Integration of Multi-source Information
In order to accurately grasp the stability of the landslide,based on on-site survey results,the current stability of the landslide is mastered by the transfer coefficient method,and then combined with the landslide deformation data,the ISSA-KELM model and the re-standardized range method are used to evaluate the subsequent deformation law and development trends of the landslide.A comparative assess-ment between these methods is conducted to evaluate the landslide stability development trends.The case analysis results indicate that the stability coefficient of the weak deformation area ranges from 1.11-1.39,while in the strong deformation zone,it ranges from1.03-1.23,indicating a state from marginally stable to stable.Regarding deformation trend assessments,the Hurst index range of the cumulative de-formation sequence is 0.641-0.821,and the Hurst index range of the deformation rate sequence is 0.448-0.506,indicating that there are certain differences in the deformation development characteris-tics at different locations of the landslide,however,the cumulative deformation shows a continuous in-creasing trend,which is consistent with the deformation prediction results.Therefore,it can be conclu-ded that the subsequent landslide stability will tend towards unfavorable development trends,posing large potential instability risks in some parts.
