利用横波分裂分析获取地下介质的各向异性参数,已成为研究壳幔介质变形特征最为有效的方法之一。本文首先介绍横波分裂理论方程的推导过程;然后阐述目前几种较为常用的拾取横波分裂参数的方法;最后总结近年来横波分裂分析方法的发展现状及其在地壳介质各向异性研究方面取得的成果。我们认为尽管横波分裂分析方法被广泛应用于地壳介质各向异性研究,但是它也存在一些固有的局限性,期望未来能发展一种更为可靠、有效的方法以及数据处理流程来准确拾取横波分裂参数。
The use of shear wave splitting analysis to obtain the anisotropy parameters of underground media has become one of the most effective methods for studying the deformation characteristics of the crust and mantle medium. This paper first introduces the derivation process of the theoretical equation of shear wave splitting; then, it expatiates several commonly used methods for picking up shear wave splitting parameters; finally summarizes the recent development of shear wave splitting analysis and its achievements in anisotropy of crustal media . We believe that although shear wave splitting analysis is widely used in the study of anisotropy of crust, it also has some inherent limitations. In the future, it is expected to develop a more reliable and effective method and data processing flow to accurately pick up shear-wave splitting parameter.
