| 摘 要： | 本文通过X光摄影观察无限介质(土)中条形装药爆炸空腔发展的高速现象。得到了实验条件下的空腔发展规律,分析了空腔发展过程中一些重要现象。实验表明:空腔发展符合幂函数规律:空腔运动过程受装药的传爆特征、空腔长径比和裂缝出现时间的影响、空腔最终形状与起爆端位置无关。

| Abstract: | In this paper,the high-speed phenomenon of the cavity growth are observed by means of the flash X-ray photograph when a strip-shaped explosive charge explodes inside unbounded medium (soil).The cavity growth curve has been got on this experimental conditions,and some important phenomenon have been analysed.According to the experimental results,the development of the cavity follows the power law.The movement process of the cavity is influenced by the features of detonation propogation of the explosive charge,the ratio of length-to-diameter of the cavity,and the time at which the cracks appear etc. |
