Buckling　failure　is　one　of　the　classical　types　of　catastrophic　landslides　developing　on　inclination-paralleled　rock　slopes,　which　is　mainly　governed　by　its　self-weight,　earthquake　and　ground　water.　However,　nearly　none　of　the　existing　studies　fully　consider　the　influence　of　slope　self-weight,　earthquake　and　ground　water　on　the　mechanical　model　of　buckling　failure.　In　this　paper,　based　on　energy　equilibrium　principle　and　elastoplastic　slab　theory,　a　thorough　mechanical　analysis　on　bucking　slopes　has　been　carried　out.　Furthermore,　an　analytical　solution　for　slip　bucking　failure　of　rock　slopes　has　been　proposed,　which　fully　considers　the　effect　of　slope　self-weight,　seismic　force　and　hydrostatic　pressure.　Finally,　the　methodology　is　used　to　conduct　comparative　analysis　with　other　analytical　solutions　for　three　practical　buckling　studies.　The　results　show　that　the　proposed　approach　is　capable　of　providing　a　more　accurate　and　reasonable　evaluation　for　stability　of　rock　slopes　with　potential　buckling　failure.　©　2024　Techno-Press,　Ltd.
