The Numerical Simulation of Effect of Parameters for Bolts on Slope Stability

In order to analyze the influence of bolt supporting parameters on the stability of slope, based on the limit equilibrium method to establish model of slope and calculated the safety factor of slope. Research shows that: (1) As the bolt length increases, the safety factor of slope increases gradually, then the length of anchor bolt can be used as the design length when the safety factor can meet the standard requirement.(2) With the increase of the anchor Angle, the safety factor of slope present the trend of first increasing and then decreasing, when bolt spacing increased to a certain value, the safety factor of slope reduce significantly.(3)In this paper, the analysis method of slope bolting parameters on its effect to the stability is simple and strong operational, which can provide a reference for related engineering personnel.
