| 摘 要： | 本文通过对边坡基底岩石振动因素的分析, 建立了单一滑面滑体受基底岩石强迫振动的模型, 采用非线性动力学方程描述滑体的变形规律, 分析了基底岩石振动过程中导致滑体移动的原因。指出在一个频带范围和力幅范围内, 基底的振动, 会引起潜在滑体位移突跳, 在滑面的法向方向上张开, 切向上错动而诱发滑坡。

| Abstract: | The factors for slope base rock vibration are analyzed in this paper, and a model is set up for single fault according to forced vibration of rock. The deformation law is described by using nonlinear dynamic equation, and causes for the slope movement are given while the rock is vibrating. It points out that the displacement could jump in a range of frequency and force amplitude, at the same time, the normal fault can open and the fault can stagger. |
