Summary Studying seismic wave propagation across rock masses and the induced ground motion is an important topic, which receives considerable attention in design construction of underground cavern/tunnel constructions mining activities. The current study investigates a mass with one fault using recursive approach. rocks beside are assumed as viscoelastic media quality factors, Q p s . Two kinds interactions between stress waves discontinuity free surface analyzed, respectively. As result...
High primary rock stress can limit the generation of cracks caused by blasting, and blasting usually shows different breaking states under conditions. There are a large number naturally formed joints in mass, due to limitations laboratory tests, numerical model jointed mass was established using LS-DYNA software investigate evolution damage various in-situ stresses open joints. In this simulation, Lagrange-Euler (ALE) procedure equation state (JWL) that defines explosive materials, study...
