摘要
本文基于分形几何及损伤力学的有关原理，提出了爆破破碎的分形损伤模型，并在此基础上建立了爆破破碎的块度预测模型。现场试验结果与模拟结果的一致性说明了模型的合理性。
Based on the relative principles of fragmentation geometry and fracture mechanics, a fragmentation model of fracture after blasting is proposed. The forecast model of frag size by blasting has been established also on these bases. The test results are in accordance with the simulation results. This fact shows that the model is reasonable.
