1 台阶爆破中不连续面的方向、连续性和倾角对负载层破碎影响的模拟研究 (ＡｌｉＭｏｔａｚａｖｉ,Ｐ Ｄ Ｋａｔｓａｂａｎｉｓ———加拿大 )本文主要介绍了炮孔扩张动态模型的开发。该模型与石 (根华 )的不连续变形分析 (ＤＤＡ)程序 (1988)配合使用。所开发的模型中考虑了
Simulation study on the influence of discontinuity direction, continuity and dip on the crushing of the load in a bench blasting (AliMotazavi, P D Katsabanis --- Canada) This paper mainly introduces the development of the dynamic model of borehole dilation. This model is used in conjunction with the Stone (Roots) Discontinuous Deformation Analysis (DDA) program (1988). The model developed has been considered
