Abstract: Slope failures or even landslides are often triggered by improper excavation in high slopes cutting, whereas pre-reinforced anchor bolt presents an effective stabilization method. A new method is proposed for the design of pre-reinforced anchor bolt for retaining high cutting slopes. Pre-reinforced anchor bolt can stabilize the slope by constraining slope deformation and development of stress relief from overburden removal. The interaction as well as force transfer mechanism between bolt and rock mass are studied; and the results provide theoretical basis for the design of pre-reinforced anchor bolt.

Key words: high cutting slope, pre-reinforced anchor bolt, interaction mechanism
