The Numerical Simulation Of The Attenuation Of Cut-Blasting Wave In Rocks With ALE Method

摘要：

Generally speaking, the most influential factor of portal excavation is the detonation wave of cut blasting in rock. With the ANSYS/LS-DYNA program, this paper researches on the three-dimension simulation of dynamic response with the method of ALE(arbitrary lagrangian-eulerian). And the selection of the penalty factor in ALE method is studied. Finally the optimization model is used to analyze the processing of cut blasting. The law of shock-wave stress decay of numerical calculation is consistent with the empirical formula calculated. This method can be used as reference for simulating the processing of blasting in rock.
