摘要(Abstract):
利用大型有限元程序对导爆索水孔爆破进行了数值模拟,客观再现了混凝土爆破的物理过程;研究了爆炸应力波在混凝土介质中的传播规律。从而有助于深入了解混凝土爆破损伤破坏过程和导爆索水孔爆破的作用机理,为爆破理论研究和工程设计提供了一种有效方法。
The present paper simulated numerically water hole blasting with detonating fuse by the use of large finite element analysis software,representing the physical procedure of concrete blasting.The propagation of the blasting stress wave in concrete was studied.It not only helps further understanding of concrete blasting damage process and water hole blasting mechanism,but also provides an effective method for the study of blasting theory and engineering design.
