Slope stability problem is one of the classical problems, while it is still in research and development to reveal complex dynamic response characteristic and failure behavior. Especially, it is difficult to estimate the stability of natural slope due to complex geology, strata, geotechnical property with large variability. In this research, two large slope models were constructed and a series of shaking table tests was carried out to reveal the dynamic response characteristic and failure behavior of natural slopes using a large shaking table. As a result, the dynamic response of the slope model was changed due to phase difference between the horizontal and vertical accelerations. Moreover, generation of a slip surface in the slope could be successfully measured so that the failure behavior of the slope model was clearly shown.
