摘　　要：围岩位移是反映地下结构稳定性的重要参数。而锚杆工作荷载是围岩与锚杆相互作用的集中体现,并且它能够利用动态无损检测方法确定。简要论述了锚杆支护作用原理和锚杆工作荷载的动态测定技术,通过相似模拟试验数据分析,初步探讨了围岩变形和锚杆工作荷载二者的对应关系,由此对巷道围岩稳定性进行了评价。Displacement of surrounding rock is an important parameter reflecting the stability of underground structure, and working load of bolts is the embodiment of interaction of surrounding rock and bolts. The working load can be obtained by nondestructive testing. The mechanism of bolt anchoring and nondestructive testing of bolts are introduced briefly, the correlation of deformation of surrounding rock and working load of bolt is discussed by equivalent material simulation and data analysis, and the stability of surrounding rock is evaluated.
