摘　　要：提出了三维非连续变形分析方法中锚杆的简化模型，给出了相应的算法和公式。算例表明，该模型能较好地反映锚杆的加固效果。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.
