This　paper　presents　a　study　of　the　failure　mechanism　and　control　measures　for　a　seismically　induced　landslide　along　the　Wanzhou-Liangping　expressway　in　China.　It　is　shown　that　the　dominant　cause　of　the　slope　stability　problem　is　the　original　inappropriate　geometry　of　the　slope.　Slope　stability　analyses　were　performed　using　Spencer＇s　method　incorporated　with　the　pseudostatic　method,　which　showed　that　the　rock　slope　was　unstable　after　the　Wenchuan　earthquake,　and　the　stability　of　the　studied　area　was　governed　mainly　by　the　significant　potential　of　deep　sliding.　Measures　to　stabilize　unstable　zones　include　resloping　and　unloading　the　slope,　installing　rock　anchors　and　a　retaining　wall,　improving　drainage,　and　vegetating　bare　areas.　The　results　indicate　that　the　measures　were　effective　in　controlling　the　landslide.
