Rock and Soil Mechanics

Based on the typical loess plateau slope of Kongtong district, Pingliang city, a 1:25 large-scale shaking table test is designed and accomplished using the conceptual model of the slopes with or without cracks. On the premise of satisfying the similarity principle, the dynamic response characteristics of model slopes of two kinds of structures are analyzed by inputting seismic waves in horizontal direction and vertical direction with different amplitudes. Results show that the horizontal and vertical seismic waves have obvious nonlinear amplification along the slope surface and the internal vertical direction, which reach the maximum value at the top of the …
