摘要
以透明试件受压破裂过程模拟均匀岩体的破裂过程 ,用实时全息干涉摄影系统记录试件应力场分布及其变化 ,用瞬态波形自动记录仪记录微破裂的位置和强度 .通过两种方式所获数据来探索地震微破裂成核过程与应力场关系 .
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.
