摘　　要：矿井矩形巷道支护往往使用时间长、支护效果差、维护成本高;采用FLAC3D数值模拟软件等方法分析探讨锚杆锚索支护强度和稳定性;拟定锚杆锚索联合支护方案;现场应用表明,支护效果良好,充分发挥了围岩承载能力和锚杆支护强度高的优势。Aiming at long service life,high maintenance cost and bad support effect of rectangle roadway support,the author proposes the combined bolt-and-cable support by analysis of the support strength and stability of bolt and cable through FLAC3D numerical simulation,which can exploit the advantages of bearing capacity of surrounding and high strength of bolting support to the full with good support effect in field application.

关 键 词：力学模型 数值模拟 围岩稳定性 锚杆锚索联合支护
