摘要
通过单轴SHPB实验,对大量花岗岩和大理岩试样的动态抗压强度、纵波波速进行了测试,对实验数据的计算表明:抗压强度的离散性较小,偏离系数只有20%左右,纵波波速和动弹性模量的离散性较大,达到了40%以上.
Based on uniaxial SHPB experiment, the dynamic compressive strength and longitudinal wave speed were obtained for a large number of granite and marble samples. Calculation of experimental data exhibits only about 20% of deviation coefficient for the compressive strength and more than 40% for longitudinal wave speed and dynamic elastic modulus.
