For a binary structure slope with soil layer on the top and rock bottom, during rainfall process, surface runoff will cause water loss damage to environment. When rainwater infiltrates into slope, pore pressure in gradually increases, shear strength of decreases, weak zone is formed at soil–rock interface, which has significant impact stability slope. Therefore, study under conditions, we used theoretical analysis, indoor model tests, numerical simulations conduct comprehensive exploration this issue, following conclusions were formed: shallow greater than that deep layer, toe slope; as gradient time when begins respond speeds up; displacement first occurs lower part then middle, finally upper part; each point up increase form small mainly flow sliding, process continuous; large sliding overall continuous sudden; fails, includes internal but small, relative interface cannot be formed; gradients are (30° 40°), decreases continuously from no formed. The larger values plastic strain occur middle parts there formation zone, mode sliding; (50° 60°), largest part, also forming penetrates through soil–soil rock–soil layers. upper, formed, modes carried out typical actual consistent results obtained.
