In order to analyze the characteristics of buckling failure of consequent rock slope, a mechanical model considering the influences of hydraulic pressure and earthquake was established according to the failure mode of multi-layered stratified rock slope. Based on the proposed model and the special function theory, a theoretical equation of the yielding curve was deduced to solve the critical length and the yielding position of consequent rock slope. The influences of the parameters such as elastic modulus of rock, cohesive strength and friction angle of slide surface, thickness and angle of rock layer on the critical length were studied. Comparison between the theoretical results and the practical results shows that the theory has excellent rationality.
