锚网支护理论的新探索
The New Exploration of Bolting With Wire Mesh Theory
-
摘要: 巷道围岩具有一定的自承能力,支护工作正是在进一步提高这种自稳能力,若把巷道顶部的岩石看作是连续岩梁,锚杆的作用就是挤压加固这一岩梁,当岩梁的厚度达到一定程度时,其中必然隐藏着1个隐形拱。通过计算和试验验证了是岩梁起作用还是隐形拱起作用。Abstract: The surrounding rock of roadway has the bearing capacity, the supporting work is to further improve the self stable ability. if the rock at the top of the roadway is regarded as continuous rock beams, the role of bolt is to squeeze and reinforce the rock beam. when the thickness of the rock beam reaches to a certain degree, which will hide a stealth arch. The paper verified that the effect is from rock beams or invisible arch.
