Abstract

This paper aims to investigate the seismic motion characteristics of bedrock and overburden layer slope with the prototype model taken from slopes in the Zheduo Mountain in Northwest Plateau of Sichuan Province, China. Based on dimensional analysis and similarity principle, two model tests with different slope angles were carried out. A transfer function analysis method was proposed to interpret the results from shaking table tests. After eliminating trend terms and signal filtering, the time-domain acceleration was transformed into frequency domain. Then the transfer function was calculated by an average periodic chart. The variation of transfer function from different positions was analyzed by Pearson correlation coefficient, and the least square iteration method was used for modal analysis. The effect of seismic intensity on the dynamic response was highlighted. It is found that the transfer function obviously changes when the slopes are destroyed. Results from modal analysis show that the natural frequency decreases with the increase of the excitation intensity, and the damping ratio increases due to slope damage.
