To investigate the dynamic damage evolution characteristics of bank slopes with serrated structural planes, the shaking table model test and the numerical simulation were utilized. The main findings indicate that under continuous seismic loads, the deformation of the bank slope increased, particularly around the hydro-fluctuation belt, accompanying by the pore water pressure rising. The soil pressure increased and then decreased showed dynamic variation characteristics. As the undulation angle of the serrated structural planes increased (30°, 45°, and 60°), the failure modes were climbing, climbing-gnawing, and gnawing respectively. The first-order natural frequency was used to calculate the damage degree (D_d) of the bank slope. During microseisms and small earthquakes, it was discovered that the evolution of D_d followed the “S” shape, which was fitted by a logic function. Additionally, the quadratic function was used to fit the D_d during moderately strong earthquakes. Through the numerical simulation, the variation characteristics of safety factors (S_f) for slopes with serrated structural planes and slopes with straight structural planes were compared. Under continuous seismic loads, the S_f of slopes with straight structural planes reduce stalely, whereas the S_f for slopes with serrated structural planes was greater than the former and the reduction rate was increasing.

为了研究锯齿状结构面岸坡的动力损伤演化特征，采用振动台模型试验和数值模拟的方法。主要研究结果表明，在连续地震荷载作用下，岸坡变形增大，尤其是水力波动带周围，伴随着孔隙水压力的上升。土压力呈现先升高后降低的动态变化特征。随着锯齿状结构面起伏角的增大（30°、45°和60°），破坏模式分别为爬升、爬爬-啃咬和啃咬。采用一阶固有频率计算岸坡的损伤度（ D _{d ）。}在微震和小地震中，人们发现D _d的演化遵循“S”形，并由逻辑函数拟合。此外，使用二次函数来拟合中强地震期间的D _{d 。}通过数值模拟，比较了锯齿状结构面边坡和直线结构面边坡安全系数（ S _{f ）的变化特征。}在连续地震荷载作用下，直结构面边坡的S _{f逐渐减小，而锯齿状结构面边坡的}S _f大于前者，且减小幅度不断增大。
