A systematic dynamic triaxial series of tests on replicated rough rock joints were carried out, and results clearly highlight the strength attenuation as a function of joint degradation with respect to the number of loading cycles. A novel semi-empirical mathematical model to evaluate the equivalent dynamic shear strength $(EDSS)$ of rock joint is proposed and validated with experimental results based on two sets of rock joints using rough (JRC = 12.6) and relatively smoother (JRC = 7.2) joint specimens.

岩石节等效动力抗剪强度（EDSS）的半经验分析模型

对重复的粗糙岩石节理进行了系统的动态三轴试验，结果清楚地表明了强度衰减与节理相对于荷载循环次数的关系。评估等效动态抗剪强度的新型半经验数学模型$（Ed\mathrm{小号}\mathrm{小号}）$ 基于两组岩石节理，使用粗糙（JRC = 12.6）和相对较光滑（JRC = 7.2）节理标本，提出并验证了岩石节理的实验结果。
