摘要
以现有支护方式、支护构件和协同支护理论为基础,在不考虑原岩应力的条件下,应用FLAC3D模拟软件对锚杆、锚索不同预应力值匹配方案进行模拟支护,获得合理预应力值匹配方案,并进行实地实验,获得良好支护效果。
Based on existing support forms, support components and the theory of synergetic, without considering the original rock stress, using software FLAC3D stimulated support in different matching schemes of pretensioned stress bolts and cables, and reasonable matching schemes of prestress value were obtained. Then good support effects were acquired by doing field experiments.
