地震动力作用下堆积体边坡的变形破坏受多种因素影响，为研究基-覆界面及坡面倾角对松散堆积体边坡的动力响应影响，通过室内物理模型试验，模拟了水平向振动荷载作用下包含不同倾角的基-覆界面和坡面的堆积体边坡的变形破坏过程。试验结果表明，堆积体边坡的破坏模式由基-覆界面及坡面倾角共同控制，当基-覆界面倾角在一定范围内（<15°）时边坡只发生浅表部局部滑塌破坏，不会发生沿基-覆界面的整体下滑；随着基-覆界面倾角的增大，边坡破坏形式由局部滑塌逐渐转变为以整体下滑为主；坡面坡度控制着边坡局部滑塌的范围。

Under the action of earthquake, the deformation and failure mode of the deposit slope depends on many factors. To study the influence of the inclination of slope surface and rock-soil boundary on the dynamic response of the deposit slope, a model test using a horizontal shaking table was conducted to simulate the failure process and dynamic response of the deposit slope under different inclination conditions. The results show that the failure mode of the deposit slope was controlled by both slope surface and rock-soil boundary. When the dip angle of the rock-soil boundary was in a certain extent (less than 20°), only local collapse in the slope occurred. As the dip angle of the rock-soil boundary increased, the failure mode of the deposit slope gradually turned from local collapse to entire sliding. Moreover, the inclination of slope surface controlled the extent of collapse.
