Stability prediction for bedded rock slopes under seismic loading is very important for landslide hazard assessment. To clarify the dynamic behaviors and damage mechanism of dip bedded slope, shaking table tests and its prototype simulation analyses were performed. Shaking table tests were conducted to analysis the acceleration dynamic response firstly and then the discontinuous deformation analysis (DDA) method was used to reproduce the test results, and study the influence of vertical earthquake on the dynamic response of dip bedded rock slope. Both the two methods results reveal that the amplification coefficients increase with increasing acceleration amplitude under sinusoidal waves shaking condition, and show an increased trend with the relation height. With Wenchaun waves loading, the discontinuous characteristics between the test model and numerical model are consistent, the dynamic responses of the slope tops are strong, and it is easy to be destroyed. Compare the failure mechanism of the slope between shaking table test and numerical method, the damage areas both the numerical model and test model are the nearly identical, and the failure modes of two models are mainly the cracking sliding failure. Moreover, with horizontal and vertical earthquake loading, the acceleration response on the numerical slope top is strong, and the maximum peak acceleration amplification factors are at the leading and rear edges of the slope top. In overall, the dynamic response of the slope surface is more significant than that inside the slope. However, with an increase of amplitude, acceleration responses are different with different directional loading, the acceleration response with horizontal loading is stronger than with vertical loading.

应用非连续变形分析（DDA）和振动台试验研究浸入层状岩质边坡的动力响应

地震作用下层状岩质边坡的稳定性预测对于滑坡灾害评估非常重要。为了弄清浸入层状边坡的动力特性和破坏机理，进行了振动台试验及其原型仿真分析。首先进行了振动台试验，以分析加速度的动力响应，然后用非连续变形分析法（DDA）重现了试验结果，并研究了竖向地震对浸润岩层边坡动力响应的影响。两种方法的结果都表明，在正弦波振动条件下，放大系数随加速度幅度的增加而增加，并随关系高度的增加而增大。随着文朝海浪的装载，试验模型与数值模型之间的不连续特性是一致的，边坡的动力响应很强，很容易被破坏。比较振动台试验和数值方法之间的边坡破坏机理，数值模型和试验模型的破坏区域基本相同，两种模型的破坏方式主要为开裂滑动破坏。此外，在水平和垂直地震荷载作用下，数值斜坡顶部的加速度响应很强，最大峰值加速度放大因子位于斜坡顶部的前缘和后缘。总体而言，斜坡表面的动力响应比斜坡内部的动力响应更重要。但是，随着振幅的增加，
