| description | The invention provides a method and a system for evaluating a slope rockfall risk under the action of an earthquake. The evaluation method comprises the steps that a vibration table applies multi-stage seismic waves to a slope model, a controller obtains a first acceleration time domain signal of each test point under each stage of seismic waves, and first vibration signal processing and second vibration signal processing are sequentially carried out on the first acceleration time domain signal of each test point under each stage of seismic waves, obtaining a first acceleration frequency-response function of each test point under each stage of seismic wave, calculating the first acceleration frequency-response function of each test point under each stage of seismic wave to obtain a morphology factor and a scale factor, and then calculating based on the morphology factors and the scale factors of all test points under each stage of seismic wave to obtain a second acceleration frequency-response function of eac |
