【摘要】 本文选用不同的加载速率对完整岩样和多块拚合岩样,进行单轴压缩试验,观测样品的变形特征和波速异常特征,初步得到拼合岩样与完整岩样在强度、变形、波速异常等方面存在着一定的差异,但在波速异常时间、尾波衰减率及频谱特征等方面又显示某些相似性。更多还原

【Abstract】 The experiments that the complete and adherent rock-samples are loaded with different rate under uniaxial compression have made. The deformation and the anomalistic wave velocity feature are observed. It was found that the difference between the complete rock-samples and the adhered rock-samples in the strength, deformation, wave-velocity anomaly etc. are existed But the similarity in the duration of wave-velocity anomaly, the attenuation ratio of the coda wave and the amplitude spectrum character etc. between the two were also existed.更多还原
