| 英文摘要 | The stability of anti-dip slopes has been a main topic of the discussion in rock mechanics and geotechnical engineering. This investigation focuses on the seismic response of the stratified anti-dip slope by 3DEC simulation. The dynamic loading, based on the measured peak ground acceleration, is applied to simulate dynamic earthquake conditions. The wavelet packet decomposition at level 3 is carried out to study the measured acceleration time-history. Amplifying coefficients of velocity and acceleration are adopted to evaluate the seismic amplifying effect of the anti-dip slope. The numerical studies reveal that the amplifying coefficients change non-linearly as the elevation increases and the changing ratio of the vertical coefficient is bigger evidently than that of the horizontal. The frequencies of the seismic input have a significant influence on the amplifying coefficients of the horizontal and vertical accelerations. The amplifying coefficient of the acceleration is mainly influenced by the seismic inputs the low and medium frequencies. The amplifying coefficient of the vertical velocity is bigger than that of the vertical velocity at the same slope elevation. At a certain elevation, only horizontal or vertical acceleration is amplified evidently rather than both. In this investigation, an experimental study was conducted to research the PPV amplifying coefficients and frequency variations of the measured signals along the anti-dip slope surface. Experimental results reveal that PPV amplifying phenomena and frequency variation are just the opposite for anti-dip slope. These numerical and experimental studies have provided some useful insights into the deformation mechanisms in anti-dip rock slope. |
