“…Whatever value the added mass coefficient takes, g is always smaller than g, and the failure acceleration should be smaller than the one by eq. (9). Not only that, frequency dependence of failure acceleration should be clearer.…”

Irreversible deformation of a coarse particle assemblage is mainly due to a change m its fabric, and this process is attended by a noticeable dilation which is confirmed through the new visualization technique (Laser-Aided Tomography: LAY). Numerical analysis by means of discrete elliptic element method (DEEM) is conducted to study the dilating process. The effect of both inter-particle slipping and rolling of embedded grains is discussed, and a simple conceptual model of slope failure, m which dilation leads to frequency dependence of the failure acceleration, is presented.
