Abstract: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.
