摘　　要：在理论分析和工程类比等的基础上对高应力巷道的支护方案进行了设计,利用FLAC3D数值软件对深部高应力巷道的开挖与支护的变形和破坏特点进行了模拟研究,得到了围岩的位移和塑性区分布等的情况,验证了锚喷支护方案的合理性和有效性。Based on the theoretical analysis and engineering analogy, the supporting scheme of high stress roadway is designed firstly. Then the deformation and failure characteristics of high stress roadway after excavation and supporting are researched in virtue of FLAC3 D,and the numerical results of displacements and plastic zones are attained. It is proved that the bolting and shotcreting support is rational and effective in the design of supporting in the high stress rock roadway.
