摘要：
Based on three-dimensional DDA method, a simple three-dimensional model was proposed to analyze rockbolting and the corresponding algorithm and formulas were given. The calculation example of the tunnel excavated shows that the model has a good reflection of the reinforcing effects of rockbolts in the longitudinal direction.
