本文用光弹性的方法记录岩石中诱发脉冲的自然振动场，并做频谱分析，这种方法可以测量波动的应力，用以显示在有限尺寸的非均匀固体或岩层结构中，由于破裂成核结构的形成而激发的声发射频谱。地声频谱方法的一个应用，是探测宏观破碎断裂面或不同岩性的断裂面。本文的结果，可导致对不同频率波的层析成像；可对矿山的岩体断层定位作出贡献，从而有助于预测矿井的灾害。在实验室中岩层破裂时声发射系列的频谱模式，可能转用于天然强震系列频谱作模拟类比。
In this paper, a photoelastic method is used to record the induced natural vibration field in the rock and do the spectral analysis. This method can measure the fluctuating stress and can be used to display in the finite-size heterogeneous solid or rock structure due to the ruptured nucleation structure Acoustic emission spectrum excited by the formation of. One of the applications of acousto-acoustic spectroscopy is the detection of macro-fractured fractures or fractures of different lithologies. The results of this paper can lead to tomographic imaging of different frequency waves; it can contribute to the fault location of the rock mass and thus help to predict mine disasters. The spectrum mode of the acoustic emission series in the rupture of rock formations in the laboratory may be transferred to the analogue of the natural series of strong earthquakes.
