本文利用 ADINA有限元程序对三维切槽孔、圆形孔爆破作了弹塑性数值分析 ,结果表明三维切槽孔爆破的破岩半径远大于圆形孔爆破 ,为三维切槽孔爆破方法提供了数值分析依据
In this paper, the finite element program of ADINA is used to elastoplastic numerical analysis of three-dimensional slotted hole and round hole blasting. The results show that the rock breaking radius of three-dimensional slotted hole blasting is much larger than that of circular hole blasting, The basis of numerical analysis
