Abstract:Based on the theory of elastic wave and the summarized geological model,a new time-frequency analysis method of the rock slope seismic stability is put forward by using the Hilbert-Huang transform. The rationality of this method has been verified by the results of shaking table test and numerical simulation. This method not only considers the amplitude-time-frequency effects,but also can forecast the safety of the slope,the time occurring the landslide and its scale. At the same time,this method can provide the valuable references for the time-history seismic design of retaining structure in the high intensity earthquake area.
