摘　　要：采用FLAC^(3D)数值模拟软件对3种工况下巷道围岩塑性区的分布特征进行对比分析,得出采用注浆+锚索的支护方案可以明显改善围岩塑性区分布,充分发挥锚索与注浆的优势。对该方案进行现场试验,并监测围岩变形及注浆前后的完整性,验证了该方案合理可行。FLAC^3D numerical simulation software is used to analyze the distribution characteristics of the plastic zone of surrounding rock under the three conditions. The result show that the plastic zone distribution of surrounding rock can be improved obviously by the support scheme of grouting and anchor cable,which can give full play to the advantages of anchor cable and grouting. The plan applied to the field, the monitoring results show that the proposed scheme is reasonable and feasible.
