| 摘 要： | 本文针对巷道围岩多被节理切割的特点，利用离散元研究了全长锚杆对节理围岩稳定性的影响。结果表明，尽早锚固，有利于围岩的稳定；同时，巷道各部位围岩的变形与破坏具有明显协同性或关联性，应预以系统考虑对围岩的加固。

| Abstract: | In this paper, the authors simulate the bolting effects on the stability of jointed rockmass by dispersive element method (DEM). The results show that it is beneficial to improve the stability of surrounding rockmass by bolt reinforce as quickly as possible after shaping the gate. Also, there are obvious relations or synergetic character between deformation and fracture of the different parts of gate. We must reinforce the surrounding rockmass systematically. |
