    METHOD FOR DETERMINING FAILURE ZONE OF SURROUNDING ROCK BY MEANS OF AXIAL STRESS MEASUREMENT OF BOLT

    • This paper summarizes the modes of axial stress distribution of bolt and analyses their mechanism.It is shown that the characteristics of shear stress acting on bolt vary in different zones zone of surrounding rock and are reflected in the axial stress distribution of bolt.Based on this relation,this paper suggests a method for defermining failure zone of surrounding rock by means of axial stress measurement of bolt.
