摘要
锚网喷(高应力让压锚杆+网喷)+鸟窝锚索+W钢带的支护模式既可以适应巷道开掘后围岩的巨大塑性变形能量需要得到一定释放的要求,又可以适应初步稳定的围岩,控制其过分变形,是一种刚柔并济的、新型的、主动的支护模式。
The supporting model of anchor net spray （high stress yield holt ＋ net spray） ＋ bird nest anchor ＋ W steel not only can adapt to the requirements of releasing large plastic deformation energy from tunnel digging of surrounding rock, but also can adapt to the initial stability of the surrounding rock, and control the excessive deformation, which is a rigid - flexible coupling, new and active sup- port mode.
