Abstract:

There are joints and cracks within rock mass on rock slopes, in contrast to soil slope which are successive failure. In comparison with the conventional pseudostatic method, the cumulative displacement (Newmark, 1965) one is a more effective approach to measure the stability of the rock slope under the influence of an earthquake.
　　In this research, the critical acceleration (Ac) was measured by means of shaking table test. However, the results show significant difference between experimental and theoretical Ac. Further research on this topic would provide the reference about rock slope earthquake engineering.
