Abstract It is shown from the in-situ monitoring and laboratory experiments that the declining，function-losing，damaging and softening，are the mechanical characteristics of rock bolts in roadways with large deformation. So the model of bolt element in FLAC3.3，a software，is amended to simulate the process of damaging and softening of rock bolts. The research result has been successfully applied in practical works.
