摘　　要：基于巷道支护中锚杆与顶板的复合作用和损伤机制分析,对锚固顶板稳定性潜力进行研究,实现了对加锚巷道顶板稳定性的定量描述。利用锚固潜力分析与数值模拟对具体巷道稳定性进行了评价,结果与实际吻合较好,该方法对类似巷道稳定性评价与巷道锚杆支护定量设计具有一定的参考价值。In this paper, based on the analysis of composite action of bolt and roof,as well as roof damage mechanism in bolted roadways, the stability potential of roof bolted is studied, and the roof stability is described quantitatively. An actual example is tested by potential analysis and numerical simulation and the result is well consistent with the practice. It has some reference value for evaluation of roof stability and quantitative design of roadways to be bolted.
