炸药混凝土中爆炸能量释放规律的研究

摘要

Based on parallel computation of explosive blasting in concrete and analysis of the numerical result as well as study on the foundational theory of explosion mechanics,a conclusion has been drawn that in the process of explosive blasting in rocks ,explosive energy is released by way of shock waves' several times reciprocate reflect in blast cavity which is full of explosion product while rock mediums are damaged and moved, and the interface loses gradually its positive expansion velocity along with the rarefaction wave in blast cavity.%通过对炸药在混凝土中爆炸的并行计算，分析其数值计算结果，并对爆炸力学基础理论进行研究后认为：炸药在土岩介质中爆炸，炸药能量将通过爆炸空腔中爆炸产物内冲击波的多次往复反射的方式进行释放，同时破坏并推动土岩介质移动，土岩介质与爆炸气体的界面在爆腔内稀疏波的作用下进行持续减速扩张运动。
