| In this study， shaking table tests of a dam-shaped model specimen with penetrated cracks were performed considering hydraulic loading from the reservoir. The dynamicbehavior of the detached block was analyzed using the pictures captured by a high-speed camera. The shaking table tests under two load conditions，with and sithout uplift pressure acting on the penetrated cracks， clarified the impact of uplift pressure on the behavior of the detached block. Numerical simulations of the dynamic behavior of the detached block during the shaking table tests were performed based on the Distinct Element Method(DEM). |
