In　order　to　analyze　the　slope　stability　under　seepage,　the　coupling　effect　of　seepage　field　and　stress　field　needs　to　be　considered.　The　ABAQUS　finite　element　program　has　good　coupling　analysis　function　of　deformation　and　seepage,　and　the　seepage　field　can　be　coupled　with　the　stress　field　directly.　So　the　ABAQUS　finite　element　program　which　is　combined　with　strength　reduction　technique　was　used　to　analyze　the　slope　stability　under　seepage,　and　the　safety　factors　of　slope　stability　were　obtained.　The　shapes　and　positions　of　seepage　of　saturated　surfaces　and　the　most　dangerous　slip　surfaces　could　be　revealed　by　using　the　strong　post　processing　functions　of　ABAQUS　program.　To　verify　the　accuracy　of　this　method,　it　was　compared　with　the　Sweden　slice　method　and　simplified　Bishop　method　that　both　were　based　on　the　traditional　limit　equilibrium　theory.　The　engineering　example　showed　that　the　strength　reduction　FEM　based　on　the　software　ABAQUS　could　overcome　the　disadvantages　of　the　traditional　limit　equilibrium　methods,　and　its　results　were　more　reasonable　and　reliable.　This　method　was　effective　to　analyze　the　complicated　problem　of　slope　stability　under　seepage,　and　the　conclusions　could　provide　references　to　the　engineering　practice.　Meanwhile,　the　influences　of　the　permeability　of　soil　on　the　positions　of　seepage　of　saturated　surfaces　and　slope　stability　were　made　a　mass　of　analysis　and　comparison,　and　the　calculation　indicated　that　choosing　finite　element　model　borders　influenced　the　positions　of　seepage　of　saturated　surfaces　and　slope　stability.　So　finite　element　modeling　should　choose　calculation　borders　reasonably.
