Abstract Flexural toppling failure is one of the most common failure types of counter-tilt slopes of layered rock. There are many questions need to be solved currently. The failure process and mechanism of the flexural toppling of counter-tilt slopes of layered rock were clarified based on the analysis of model test results. The mechanical model and stability analysis method of the flexural toppling of counter-tilt slopes of layered rock were established on the basis of the limit equilibrium theory for cantilever beams，and a special computer code was developed to provide rapid evaluation of slope stability for the flexural toppling of counter-tilt slopes of layered rock. Finally，two case studies were illustrated for practical verification of the proposed approach，and a parametric study was conducted. Some conclusions useful for design and construction of these types of slopes were drawn.

Key words： slope engineering rock layered counter-tilt slopes toppling failure limit equilibrium analytical approach
