Abstract

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.
- real-time holography,
- seismic wave,
- micro-fracture,
- stress (strain) field
