In　this　paper,　the　mitigation　strategy　of　Landslide　K227　was　summarized,　and　the　numerical　simulation　and　optimization　of　the　mitigation　stages　of　the　upper,　middle　and　lower　parts　of　the　slope　were　conducted.　The　results　of　the　comparison　of　the　field　monitoring　and　simulation　data　guided　the　process　controlling　of　slope　construction,　which　achieved　the　target　of　safety,　orderliness　and　control　at　all　the　stages　of　the　construction　and　no　hidden　risks.　The　global　safety　factor　1.10　was　suggested　to　be　the　threshold　value　to　define　the　slope　stability　under　the　comprehensive　conditions　due　to　the　need　for　stability　control　of　super-high　cut　slope　and　their　structural　durability　in　the　whole　construct　process.　The　backfilling　at　the　toe　of　the　slope　was　imperative　to　ensure　the　present　stability　during　the　construction　of　the　super-high　cut　slope.　The　timing　and　opportunity　to　adjust　the　similar　temporary　safety　precautions　should　be　prudently　determined.　Planning　in　advance　and　installation　in　time　of　two　rows　of　anti-slide　anchor　piles　were　important　to　control　the　reduction　of　stability　and　the　development　of　towing　deformation　in　up-rear　part　of　slope,　to　keep　the　safety　of　construction　process　and　to　make　the　remediation　successful.　There　are　various　potential　failure　mechanisms　in　the　treatment　to　super-high　cut　slope　with　the　transformation　of　local　and　global　deformation　of　slope.　Therefore,　multiple　plans　are　supposed　to　be　simulated　and　adjusted　in　order　to　maintain　the　compatibility　of　local　and　global　deformation.　The　passive　mode　of　the　design　adjustment　due　to　the　slope　failure　need　be　to　transformed　into　the　active　one　of　simulating　the　slope　deformation　in　advance,　which　can　control　the　secondary　disasters　during　the　period　of　construction　of　cut　slopes.　©　2017,　Science　Press.　All　right　reserved.
