摘要
以巷道围岩应力场为零为基础,采用FLAC3D模拟手段,模拟支护参数对预应力场的影响,支护参数主要包括锚杆长度、锚杆间距、锚杆安装角度、锚固方式和锚杆预应力。并以模拟结果和实践为基础,提出该六要素在选择过程中应考虑的因素及重要性。
Without considering conditions of the stress of origin rock, using FLAC3D software simulates the influence of the anchor length, the distance between the anchor bolt, the bolt installed angle, and anchorage way on pretensioned distribution of prestressed anchors. Based on simulation results and practice, putting forward the considering factors and importance of six elements in the process of the choice to provide scientific guidance.
