| Abstract: | The fracture process of transparent samples are used in this paper to simulate that of a homogeneous rock mass. In order to discover relationships between the micro_fracture nucleation and its surrounding stress field, a real_time holographic optical setup is used to record the distribution and variations of the samples' stress fields and the transient wave_form automatic recorder is used to record the location and intensity of the micro_fractures. The initial research has brought about some phenomena worthy of notice. This method has provided us with a new approach to make a seismic experimental research. |
