| 摘 要： | 利用一级轻气炮对石灰岩进行冲击损伤实验,并对回收试样进行超声波测试,在此基础上建立了损伤度与碰撞速度、峰值压力及插入损伤的拟合关系。结果表明,插入损伤能很好地反映岩石的损伤程度。

| Abstract: | Impact damage experiments on limestone specimens were carried out with one-stage light-gas gun,and the resulting damaged rocks were subjected to ultrasonic tests.Based on the results,fitting relations between damage degree and impact velocity,peak pressure and insert damage of the sample were established,indicating that insert damage can reflect the damage degree of rock well. |
