针对覆盖层型边坡，提出了一种新的地震作用下边坡稳定性分析方法，并利用振动台试验和数值模拟结果验证了该方法的合理性。该方法可以考虑地震波的持续时间、频率和振幅对边坡稳定性的影响。同时，振动台试验和数值模拟结果表明，该边坡的滑动过程是一个平衡渐进的过程，滑坡机理分析结果表明，结构面的不一致运动和强度降低是诱发滑坡的两个主要因素。
Aiming at the covering-layer-type slope, a new analysis method of seismic slope stability is put forward, and its rationality is verified by using results of shaking table tests and numerical simulations. This method can consider the effect of shaking duration, and frequency and amplitude of the seismic waves on the stability of the slope. At the same time, the results of shaking table tests and the numerical simulations show that the sliding process of the two-side slope is a balanced and progressive process, and the landslide mechanism analysis results show that non-consistent movement and reduction of strength of the structural plane are two of the major influence factors, which induce the landslide.
