%X In order to see into stability of rock mass during crack propagation,and the fracture toughness increment of crack by bolt which will prevent propagation of crack,the relationship of shear strength of bolted joint plane and bolting parameters in compressive-shear stress state is set up. Furthermore,sub-crack propagation mechanics model is developed on the basis of catastrophe theory,which is significant for understanding crack propagation process,assessing stability of rockmass,and taking reasonable bolting measures in advance.
