Abstract

Based on the wave propagation theory on the jointed media, a dynamic damage model of the jointed medium is developed based on theoretical analyses and model tests to describe the wave propagation behavior on the jointed rock mass under the blasting pulse. The presented model is capable of describing the behavior of dynamic response of the microjoints and its interaction with wave propagation properties, as well as the consideration of the degradation of the material stiffness and strength, which cannot be described by the classical continuum damage mechanics theory. Comparisons between the proposed model and the test results are also discussed.
