| 摘 要： | 探讨了在Ｈｏｐｋｉｎｓｏｎ压杆装置上进行岩石长杆冲击实验。用多组埋入式聚偏四氟乙烯薄膜应力计，进行了波衰减的测量，获得了大理岩、砂岩在干燥、饱水、饱油情况下的衰减系数。对实测波形运用拉格朗日分析和路径线方法获取了大理岩、砂岩动态本构关系。

| Abstract: | By use of Hopkinson bar apparatus,the paper studies the shock waves experimentof long rock testing samples. Wave attenuation has been measured with PVDF gauges,the atten-uation constants of marbles and shales in the conditions of dry, water-satureted and oil-saturatedhave been obtained.The measured waves have been analysed using Lagrange and path curvemethods and we get the dynamic constitutive relations of marble and shale. |

| Keywords: | path curve Lagrange analyse dynamic constitution stress wave attenuation |
