Dynamic Responses of Weathered Rock Slopes Under Harmonic Waves
Dynamic loads with different peak accelerations often lead to slope damage and failure. The dynamic responses of slopes must be analyzed, and the degree of damage evaluated. Here, the dynamic response and failure mode of a weathered rock slope under the action of harmonic waves with different peak accelerations was studied using the shaking table test. Three quantitative indexes of slope damage were then proposed. The main result is that the acceleration response of the slope is characterized by “elevation” and “aspect” effects. Slope failure can be divided into four stages: 1) the elastoplastic change of the rock and soil, 2) the occurrence of cracks inside the slope body, 3) the fracture was connected stage, and 4) the movement of the sliding body. Slope damage was identified firstly according to the change of average natural frequency, secondly according to slope displacement, and thirdly the test phenomena.
