After reviewing the classic criteria of structural damage due to ground vibrations caused. by rock, blasting, their assumptions, and limitations are pointed out, particularity when dynamic stability analysis, are to be performed.
A new criteria, based on the balance between the magnitude of the dynamic stresses carried by the vibrating wave and the dynamic strength of the medium is proposed. Due to its simplicity and direct application to field conditions of rock blasting, the method seems appropriate, to predict failure in any type of structure, provided their dynamic properties are known.
Confirmation of the allowable limits of vibration proposed by the empirical, criteria is accomplished and examples of application of the new criterion to, dam structures and rock volumes situated in the proximity of blasting works are presented.
