| 英文摘要 | Analysis of the vibration characteristics of slope is the basis of dynamic analysis of slope; therefore, it has an important engineering significance. In this paper, ideal joint rock slope was studied by the modal analysis and harmonic response analysis module in the ANSYS software, meanwhile, the section of the model size and the effects of the structural parameters on the vibration characteristics of slope were also discussed. The results show that the stiffness of the structural surface is the key factors that affect the vibration characteristics of slope, and with the stiffness of structural surface increases, the first modal shape of slope was changed from dislocation vibration that along the structural surface to horizontal vibration. Only the first natural frequency can be excited the "resonance" phenomenon in the horizontal direction under the seismic load. Therefore, the joint slope is more easily to be excited "resonance" under earthquake load because of the first natural frequency of joint slope is smaller than homogeneous slope; moreover, this is consistent to the investigation results of Wenchuan Earthquake. |
