摘要:
为完善炸药混凝土内爆炸理论、提高其做功能力,该文建立混凝土内部炸药爆炸模型。在混凝土内爆过程中及冲击载荷下,对TNT炸药及PBX类炸药对混凝土的毁伤破坏效应,利用混凝土动力学损伤破坏模型和光滑粒子动力学方法进行数值研究。该文定量地给出了混凝土内爆炸损伤的类型为抛掷内爆炸和松动内爆炸。数值分析了混凝土介质的运动特性,确定了混凝土内爆炸的最佳条件。在掩埋情况下,炸药埋深0.45H时,内爆效果较好。
Abstract:
To perfect the theory of explosive internal-blast of concretes and to improve its working,a model is established about the explosive internal-blast of concretes.In the internal-blast process of concretes and under dynamic load of impulsion,the dynamical damage effect of concretes by TNT and PBX explosives is researched numerically using the dynamical damage model of concretes and smoothed particle hydrodynamic method.The quantitative calculation results show that the damage types of internal-blast for concretes are throw internal-blast and loose internal-blast.The motion characteristics of concrete medium are numerically analyzed,and the optimum condition for internal-blast is determined.The effect of internal-blast of concretes is the best when the buried depth of explosives is 0.45H in the buried condition.
