摘      要：The dynamic shear strength of rocks is required for the earthquake-resistant design of nuclear power plants in *** research aims to propose a mathematical model for estimating the dynamic strength and to validate the *** different types of specimens were prepared for the model validation,and the monotonic and cyclic loading tests were conducted to obtain the mathematical model ***,multistep cyclic loading tests were performed,followed by simulations using the mathematical *** test results demonstrated that the dynamic shear strength exceeded the static shear strength,which agreed with previous ***,the dynamic shear strength calculated using the mathematical model was generally consistent with that obtained from the experimental data.
