【Abstract】 LS-DYNA3D finite element program was used to simulate dumping effect of in-situ pre-split crack. The simulation results were adopted to compare with the testing data of in-situ blasting in a mine so as to analyze the pre-split crack dumping effect and to give a reference to design and construction of engineering blasting.更多还原
