摘要: 从岩石的变形特性出发，通过等效裂纹模型的建立，给出了岩石在单轴加载、卸载和重加载过程中岩石声学特性的理论模型；对大理岩、灰岩和玄武岩三种岩石进行了单轴循环加载过程中的超声波测试实验，实验结果与理论计算基本吻合。

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.
