Abstract Laboratory experiments on monitoring the acoustic emission signals and time variations of volumetric activity of radon during uniaxial loading of a granite sample up to its fracture have been carried out. Based on the results of the experiments, the amplitude-frequency spectra of acoustic emission are constructed for four successive time instants. Based on the quantitative interpretation of the data, the time variations in the structural parameters of the rock, the pattern of evolution of the fracture process, and the regularities in the changes of separate stages of this process are studied.

氡体积活度声发射和时间变化观测的岩石破裂过程演化特征

摘要 进行了在花岗岩样品单轴加载直至断裂期间监测氡的声发射信号和体积活度随时间变化的实验室实验。根据实验结果，构建了四个连续时间瞬间的声发射幅频谱。在对数据进行定量解释的基础上，研究了岩石结构参数的时间变化、断裂过程的演化规律以及该过程各阶段的变化规律。
