Marginal spectrum peak and characteristic frequency curve of each measuring point near the sliding surface under the action of earthquakes with different intensities. (a) Marginal spectrum peak and characteristic frequency curve of each measuring point under low-intensity earthquake. (b) Marginal spectrum peak and characteristic frequency curve of each measuring point under medium-intensity earthquake. (c) Marginal spectrum peak and characteristic frequency curve of each measuring point under high-intensity earthquake.
