Abstract

The process of rock blasting involves large deformation of rock mass,material nonlinear,and so on, the research on the mechanism of it is still in the stage of exploration at present.This article attempts to analyze the propagating of the stress wave in the explosions from the microscopic view. We simulate the whole transmission process of explosive stress wave,and obtain the change laws between stress wave with the distances from center of explosion on the basis of the previous theoretical analysis and model experiment. And then compared the results of model calculation with the result of this experiment,The result show the applicability of the simulation results.This paper discloses the motion of particles in the blast from the microscopic view, it is helpful for us to study more complicated geotechnical problem in meso-scale simulation, so as to provide experience for reference.
