| 摘 要： | 为了揭示聚能爆炸射流切割和破碎岩石的内在一般规律 ,利用超动态应变试验测试了岩石在点状聚能射流作用下的受力情况。试验表明 ,岩石在聚能射流作用下 ,除射流直接作用处为射流冲击、高温融熔破坏外 ,其整体破坏以切向拉伸破坏为主。另外 ,炸高、岩石是否受约束均会对聚能射流侵彻岩石的效果产生显著影响。

| Abstract: | In this paper, ultra dynamic strain test is used to investigate the condition of rock penetration by shaped charge jet.The test result shows that except the jet penetration points wrecked by shaped charge jet impact and high temperature melting,the rock is mainly destroyed by tangential extensional force.Moreover,the distance between shaped charge and rock face,and rock bound degree all affect jet penetration in rock.It is of benefit for the test to uncover the general laws of the deformation of the rock cut by shaped charge jet. |
