Abstract： [Purposes] The objectives of this study are to ascertain the fundamental characteristics of the landslide，analyze its contributing factors，and propose aremediation plan that is safe，reliable，economically reasonable，and technicall feasible.[Methods] Taking alandslide along an expressway in Guizhou Province as an example，an investigation was conducted based on the analysis of the landslide's geological environmental conditions，deformation characteristics，and deformation mode，utilizing methods such as topographic surveying，drilling，and geotechnical testing.[Findings]The landslide was induced by the combined effects of slope toe excavation，rainfall，and weak interlayers.Thestability coefficientof the landslide is less than 1 under heavy rainfall conditions，indicating an unstable state.[Conclusions] A comprehensive remediation plan incorporating "anti-slide retaining walls + slope surface protection + interception and drainage"is proposed.
