Research Advancements in Surface Wave Exploration

面波勘探通过对提取面波的频散曲线等观测进而反演获得探测目标信息。面波勘探技术始于20世纪60年代,但近几十年来迅猛发展,已经被广泛应用在地震灾害及火山活动预测、深部地质结构、工程施工、矿区采空区、塌陷区探测以及星体近地表结构探测等方面。为了更全面了解面波勘探技术,本文从面波勘探技术的主动震源和被动震源这两种数据类型开始,回顾基于频散曲线和水平垂直振幅谱比观测的面波勘探技术基本理论,简要介绍面波反演方法,并介绍面波勘探技术的应用领域和发展趋势和前景。

Surface wave exploration plays a vital role in obtaining target detection information by analyzing and retrieving the dispersion curve of surface waves.Although surface wave exploration technology originated in the 1960s,it has experienced significant advancements in recent decades and has found widespread applications in earthquake disaster and volcanic activity prediction,deep geological structure analysis,engineering construction,mining area and goaf assessment,subsidence area detection,and near-surface structure investigation,including celestial bodies such as stars.This paper aims to provide a comprehensive overview of surface wave exploration technology.It begins by discussing two types of data sources,namely active source and passive source,and proceeds to review the fundamental theory of surface wave exploration based on dispersion curve analysis and observations of horizontal and vertical amplitude ratios.This paper also provides a brief introduction to the surface wave inversion method.Additionally,it highlights the various application domains of surface wave exploration,outlines the current development trend,and presents future prospects for this technology.
