Abstract
In order to clarify the possibility of slope failure at existing nuclear facilities, the failure behavior based on the results of the shaking table tests under 1G field of the slope model is analyzed and the failure mechanism is clarified. Secondly, the applicability of the Material Point Method as an assessment method of the behavior is made clear. The slope model was made into 1.0 m in height, and 45 degree in inclination. The record observed at JMA Kobe by The Southern Hyogo prefecture earthquake in 1995 was used for shaking as well as the sinusoidal wave. It was found that a slip surface was formed due to the increased width and localization after connecting each area where a large shear strain was generated. In addition, it is found that the formation process of the primary slip surface which observed in the tests is properly simulated by MPM analysis.
