摘要

通过对矿山裂隙岩体锚杆注浆机理的分析，得到了节理岩体抗剪强度和最佳锚固角等本构关系。采用Flac3D软件分别对双线巷道无支护和锚杆注浆条件下的围岩巷道进行了数值模拟。模拟结果表明，锚杆+注浆支护提高了节理巷道的承载能力，改善了巷道的应力分布，限制了节理巷道围岩的变形。

Study on Numerical Simulation and Bolt Grouting Mechanism of Mine Fracture rock masses

The constitutive relation such as shear strength and optimal anchoring angle of jointed rock masses are obtained by analyzing the bolt grouting mechanism of mine fracture rock masses. The rock roadway of double-track roadway is simulated respectively by Flac3D software under the condition of no-support and bolting and grouting. The simulation results show that the support with bolting and grouting enhances the bearing capacity of jointed roadway, improves the stress station, and limits the deformation of the jointed roadway rock.
