结合延吉市八道金矿坑探工程，利用FLAC3D软件建立坑道三维实体模型，对坑道围岩的应力分布规律、变形位移大小及塑性区分布等方面进行围岩稳定性的综合分析。然后根据分析结果对施工坑道围岩形变大的部位进行监测，为坑道施工安全及支护方案提供了一定的参考依据。
結閤延吉市八道金礦坑探工程，利用FLAC3D軟件建立坑道三維實體模型，對坑道圍巖的應力分佈規律、變形位移大小及塑性區分佈等方麵進行圍巖穩定性的綜閤分析。然後根據分析結果對施工坑道圍巖形變大的部位進行鑑測，為坑道施工安全及支護方案提供瞭一定的參攷依據。

Combined with the pit prospecting engineering of Badao gold deposit in Yanji City, the 3D solid models of the tunnel are established by using the FLAC3D software, the stress distribution regularities of the tunnel surrounding rock, the deformation displacement, the plastic area distribution and the stability of surrounding rock etc. are analyzed comprehensively. The tunnel deformation of the site where is excavating is monitored according to the results of analysis, which provides a certain reference for excavating tunnel safety and timbering schemes.
