实时全息法应用于地震基础实验的研究
|
摘要
本文介绍了将实时全息法用于地震基础实验的研究 ,实验中以透明试件受压破裂过程模拟均匀岩体的破裂过程 ,采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系统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和应力场关系 ,这种方法的成功为地震实验研究提供了一种新手段。
Application of real time holographic method to the seismic experimental study has been introduced in this paper.The fracture process of uniformity rock is simulated in a series of transparent samples in this study.In order to find out some relationships between the micro crack nucleation and its surrounding stress field distribution,the stress fields and its variations in the sample are measured by a real time holographic interferometry while the location and the intensity of the micro cracks are recorded by an automatic wave form recorder.Some noticeable phenomena have been observed.The success of this method gives a new method for experimental seismic research.
