Based on perfect elastoplastic constitutive model and Drucker-Prager yield criterion

and using ANSYS software and finite element numerical simulation technology

a finite element analysis model for bedding rock cutting slope is established. The stress

deformation and stability of the bedding rock cutting slope before and after supported by anchor are simulated and analyzed for the high bedding rock cutting slope engineering from Baishiping to Langping in Yichang to Enshi highway in the HU-RONG national main trunk. The analysis and comparison indicate that the maximum displacement of the slope at critical state is reduced ; the friction force on the most dangerous contact surface is increased; and the stability coefficient is raised when the slope is supported by anchor. So the stability of the bedding rock cutting slope can be improved to protect the slope from bedding sliding.
