| 摘 要： | 通过超声波对单轴压缩试验中岩石扩容现象的测试,分析了超声横波在不同岩石压缩过程中的传播情况。利用超声横波的特性测出岩石在压缩的不同阶段的微裂纹发展情况和体积变化情况,进一步证明了不同岩石在单轴压缩过程中扩容的时间和程度是有所差异的。

| Abstract: | In this paper the test and the spread situation of the ultrasonic S-wave in the compressing procedure with different rock samples under the condition of uniaxial compression are described.We use the S-wave to observe the crack developing and the volumetric dilatancy changes in the different stages under the uniaxial compression condition.We prove that for different rock samples in the procedure of uniaxial compression,the time and the degree of rock volumetric dilatancy are different. |

| Keywords: | ultrasonic wave volumetric dilatancy tiny crack S-wave volumetric strain |
