采用ＶＤＺＺ－１型动光弹仪，记录了在半无限板中单孔轴向孔口起爆全过程的应力波条纹。对应力场进行了定性和半定量处理，得出了应力场变化的基本规律。为进一步研究岩石爆炸破碎机理提供了参考。
The VDZZ-1 dynamic-optical projectile was used to record the stress wave fringes in the whole process of single orifice axial orifice explosion in a semi-infinite plate. The stress field was qualitative and semi-quantitative treatment, obtained the basic law of stress field changes. It provides a reference for further research on rock explosion crushing mechanism.
