英文摘要A model of a steep bedding rock slope with a slope angle of 50 degrees and rock dip angle of 55 degrees was designed and fabricated, and a large-scale shaking table test was carried out to investigate the acceleration, displacement, acoustic emission, and failure mode under earthquake action. In the vertical direction of the slope, the acceleration amplification factor significantly increased as the elevation increased. In the horizontal slope direction, the acceleration amplification factor decreased with the distance from the slope surface. Under the action of different input wave types, the acceleration response of the slope was markedly difference. The acceleration amplification factor exhibited the change law of first increasing and then decreasing with the increase in the input wave frequency, and became maximum when the frequency was 25 Hz. With the increase in the input wave amplitude, the acceleration amplification factor of the slope exhibited the trend of first increasing and then decreasing. The slope displacement and the acoustic emission parameters increased nonlinearly with the increase in the input wave amplitude, and the process can be divided into two stages: the slow increase period and the sharp increase period. Under seismic wave action, the deformation and failure evolution process of the slope included four stages: (1) the rock layer at the top of slope undergoes tension fracture; (2) the tensile cracks extend downward along the layer to form a locked segment at the toe of the slope; (3) the locked segment shear fractures through the sliding surface; (4) the slope suddenly becomes unstable and slides. The failure mode of the slope model was tension-shear sliding failure.
