摘要
对围岩和锚杆的应力之间的相互作用关系进行了详尽的分析,并通过大型有限元软件ABAQUS模拟并验证了底角锚杆的作用机理,指出加设底角锚杆可控制底板受力,减轻压力,抑制底臌的产生。
The paper has the detailed analysis of the relevance of between the stresses of surrounding rocks and anchors, undertakes the simula- tion with the large-scale finite element software ABAQUS, proves the mechanism of the anchor in floor, and points out the stress of the bottom plate can be controlled by the added anchor in floor, so as to relieve pressure and bottom swellings.
