Abstract：
The numerical calculation element of the anchor bolt is built, which is in accordance with the real situation of bolt mechanical and deformation characteristic. The Lagrange differential calculation method is used to build the jointed rock mass slope calculation model, as well as the coupling effect of anchor bolt and slope. The analysis results show that:(1)after bolted, the slope still occur large deformation, and the anchor bolt shows flexible reinforcement effect；(2)Due to the reinforcement effect of bolt, the displacement of rock mass near the joint plane does not vary much. The anchor bolt exerts the tensile effect, although this effect only occurs if the slip block moves；(3)Due to the moving of the slip block, there exists large axial force in the anchor bolt, which is intersected with the joint plane. And there exist several peak value of axial force in the bolt.
