【摘要】 本文首先简述了尾波干涉方法的基本原理,随后介绍了尾波干涉方法在研究震源位置变化和监测散射体运移状态的相关应用与进展,最后探讨了利用重复地震、人工主动源和噪声互相关函数监测地下介质波速变化的尾波干涉方法的优缺点及发展方向.尾波干涉方法基于尾波的多次散射特性,能够提取震源位置与介质的细微变化,其中介质的动态变化可为地震(火山)的孕育、形成及发展提供研究思路与指导意义.更多还原

【Abstract】 This review first presents the basic theory of coda wave interferometry(CWI),and then introduces the application and research progress of CWI in source location variation and scatter moving status.Finally the advantages and the disadvantages as well as development direction of the CWI in monitoring velocity variation of underground media are discussed by using repeating earthquakes,active sources and ambient noise cross-correlation function.Due to the characteristics of multiple scattering waves,CWI can be used to extract source locations and monitor subtle variations of media.The temporal change of media may provide us ideas and guidances of preparation and development of earthquakes or volcanoes.更多还原
