利用一级压缩空气炮进行高速平面撞击实验，分别测量了砂岩、花岗岩和石灰岩试件组成的靶板中的应力脉冲波形。利用改进的拉格朗日分析方法对应力－距离－时间的实验数据进行分析处理，得到岩石的动态本构关系，了解了岩石在强冲击载荷下的某些力学性质和变形特征 High-speed plane impact experiments were performed using a first-class compressed air gun, and the stress pulse waveforms in the target plate consisting of sandstone, granite, and limestone specimens were measured. Using the modified Lagrangian analysis method, the stress-distance-time experimental data is analyzed and processed to obtain the dynamic constitutive relation of the rock, and the mechanical properties and deformation characteristics of the rock under strong impact load are known.
