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。
In order to study the dynamic response of the slope of the loosely packed body to the dynamic response of the slope of the loosely packed body, the deformation and failure of the slope of the pile body subjected to the earthquake motions are influenced by many factors. Through the physical model tests in the laboratory, Under the action of different inclining angle of the basement - interface and the slopes of the slope of the body deformation and failure process. The experimental results show that the failure mode of the slope of the pile body is controlled by the base-cover interface and the inclination of the slope. When the inclination of the foundation-cover interface is within a certain range (<15 °), only the local surface collapse of the shallow part occurs , The overall sliding along the foundation-cladding interface will not occur. With the increase of the dip angle of the base-cladding interface, the failure form of the slope gradually changes from the partial collapse to the overall decline. The slope of the slope controls the local slip Collapse range.
