摘要：为确保公路安全施工及运营，以某顺层路堑滑坡为工程背景，开展此类滑坡灾变成因及演化流程分析，并以变形监测数据为基础，在其数据去噪处理基础上，通过稳定状态、变形及速率判据综合开展滑坡变形预警分级研究。结果表明:路堑滑坡的变形特征显著，灾害成因较为完备，且此路堑滑坡的演化流程也较为清晰；GA-Kalman滤波能有效实现滑坡变形数据去噪处理，相对其他方法优越性显著，并经三类判据综合预警分析，路堑滑坡复活段的预警等级属Ⅲ~Ⅳ级，未复活段的预警等级为Ⅰ级。研究成果可为类似滑坡工程提供参考。

Abstract：To ensure the safe construction and operation of highways,taking a certain layered road cut landslide as the engineering background,this study first analyzes the causes and evolution process of such landslide disasters.Based on deformation monitoring data,on the basis of data denoising processing,a comprehensive study on landslide deformation warning and grading is carried out through stable state,deformation,and rate criteria.The results indicate that the deformation characteristics of road cut landslides are significant,the causes of disasters are relatively complete,and the evolution process of this road cut landslide is also relatively clear;GA Kalman filtering can effectively achieve denoising of landslide deformation data,with significant advantages over other methods.After comprehensive warning analysis based on three criteria,the warning level of the resurgent section of the road cut landslide belongs to level III-IV,and the warning level of the non resurgent section is level I.Overall,the stability of the resurfacing section of the road cut landslide is poor.The research results can provide reference for similar landslide projects.
