摘要
On the basis of dynamics finite elements theory, rocky slopes with different height and gradiant are computed in the process of model analysis and time-dependent analysis of seismic acceleration by ANSYS software. Some new dynamic response laws and phenomena are found through the research. The model analysis shows that the natural vibration frequency of slope dropped as rising of slope height; while the changes of slope angle acts contrary to the natural vibration frequency. Time-dependent analysis of seismic acceleration also indicates that the displacement, speed and acceleration of slope response in the similar way. Furthermore, the slope crest displacement has a linear upward trend with the increasing in slope gradiant, besides, the attenuation effect of seismic wave and the amplification effect of slope exists at the same time. The results would have a great reference value to aseismic design of slope.
