根据期刊文献，统计了近20年来国内外声发射研究的论文，介绍了声发射的原理、机理、试样的空间定位，并结合弹性力学理论，对声发射的机理进行了分析，提出了声发射的基本概念，并对声发射的机理进行了讨论。空间六向法和四向法本文介绍了岩石声发射的现场测量方法，根据不同的取样方法，有两种取样方法，声发射的影响因素系统地阐述了声发射法在地应力测量中的应用、凯塞点的确定方法以及信号和噪声的处理技术，介绍了两种不同于传统地应力测量的方法，分析了声发射法地应力测量存在的问题及研究趋势。
Based on periodical literature,the statistics of papers on accoustic emission since recent twenty years were made.The principle and mechanism of acoustic emission,space positioning for the samples were presented.With the theory of elastic mechanics,six direction and four direction methods in space for in-situ measurement using the rock acoustic emission were derived.There are two sampling methods according to the different methods.Influence factors of acoustic emission in in-situ stress measurement,determining method of Kaiser Point and treatment technique for signal and noise were systematically expounded.Two methods which are different from the traditional in-situ measurement are introduced.Problems and research trend of the in-situ stress measurement using acoustic emission were analyzed.
