     View Summary

    The authors investigated the dynamic stability of rock slope consisting of hexagonal blocks through model tests on shaking table and evaluate their stability through dynamic limiting equilibrium method (DLEM). Experiments indicated that the failures may be toppling or sliding and, they may be of active or passive modes. Critical acceleration levels can be estimated from the limit equilibrium method if frictional properties of rock blocks and the geometry of model slopes together with appropriate consideration of failure modes.
