Slope　stability　has　been　a　key　issue　in　the　field　of　geotechnical　engineering.　Determining　the　potential　sliding　surface　of　a　slope　is　an　important　link　in　evaluating　the　stability　of　the　slope.　For　rock　slope　with　embedded　structural　plane,　the　potential　sliding　surface　is　greatly　affected　by　the　embedded　structural　plane.　When　determining　the　potential　sliding　surface,　the　influence　of　the　position　of　the　embedded　structural　plane　should　be　considered.　According　to　the　distribution　characteristics　of　the　embedded　structural　plane　of　the　rock　slope,　the　structural　plane　in　rock　slope　is　divided　into　two　types:　(1)　front　embedded　and　(2)　rear　embedded　structural　plane.　Considering　the　influence　of　two　types　of　structural　planes,　a　search　method　for　potential　sliding　surfaces　of　rock　slope　is　proposed　combined　with　the　finite　random　tracking　method.　The　location　of　the　sliding　surface　is　controlled　through　the　cut-in　point,　cut-out　point,　and　arc　height　so　that　the　range　of　search　variables　does　not　need　empirical　assumption.　An　engineering　example　is　used　to　verify　the　search　method.　The　results　show　that　the　method　could　accurately　obtain　the　potential　sliding　surface　of　the　rock　slope　with　embedded　structural　plane,　which　proves　the　effectiveness　of　the　search　method.
