Abstract: The stability analysis of counter-tilt rock slopes is a difficulty in rock slope analysis, and there are many questions need to be solved. Limit equilibrium method is the most common and relatively effective method at present. Based on the cantilever beam limit equilibrium model by D. P. Adhikary and A. V. Dyshin, the form of fracture plane and the influences of cohesion and severe of different layers are mainly modified, and an improved cantilever beam limit equilibrium model is given. Based on the new model, a new method to analyze the stability of counter-tilt rock slopes is proposed by using residual unbalance force as standard, and a comprehensive research on the influences factors of counter-tilt rock slopes is made. By doing these work, some conclusions and laws which are useful for design and construction of these type of slopes are drawn.

Key words: counter-tilt rock slope, limit equilibrium method, influencing factor
