摘　　要：通过数值模拟和TM5-855-1经验公式分别计算了集团装药爆炸的地冲击参数,以此证明模拟结果可信;对BLU-113A/B和等量集团装药爆炸引起的地冲击参数的数值模拟结果进行了对比,得出了比例爆距λ>0.7二者的冲击参数差异不大;比例爆距λ<0.3岩石峰值应力前者是后者的4倍以上的结论。First of all, the simulating results were proved to be creditable by calculating the ground shock parameters of explosion of group charge with numerical simulation and experiential formula of TM5-855-1 respectively, then, by comparing ground shock parameters caused by explosion of BLU-113A/B and equivalent group charge, it can be seen that there＇s little difference between them when λ 〉 0.7 and the former maximal rock stress was above four times bigger than the latter when λ 〈 0.3.
