Abstract
The mechanics mechanism of bolt reinforcement of joint fissure test pieces were discussed with the method of variable angle plate indoor model experiment and the deformation of bolt control of jointed slope were analyzed by numerical simulation. The results show that: the bolt reinforcement can improve not only the integrity of joint fissure rock mass, but also be a very good control of deformation of jointed slope. It establishes the foundation on the quantitative for evaluation of joint fissure rock mass deformation and stability.
