| Abstract: | This paper gives a theoretical model for ultrasonic properties of rock with microcrack under uniaxial loading, unloading and reloading, on the basis of analyzing microcrack deformations by fracture mechanical theory and setting microcrack equivalent model. The experiment of ultrasonic measurement of marble, limestone and basalt under uniaxial cycle loading has been performed.In general,the experimental results have a good agreement with the theoretical predictions. |

| Keywords: | rock ultrasonic properties uniaxial loading unloading |
