摘　　要：近年来随着背景噪声成像方法逐渐趋于成熟,随着研究理论的深入,被众多学者应用于地球深部速度结构研究中,且已取得较好的研究成果。在浅层结构研究中,获得更多的浅表物性信息将极大的提升对浅层结构的认识。噪声互相关成像方法所获得横波速度信息,对地下断层、空洞、溶洞等速度差异较大的地下结构有效识别,将有助于我们对地震等地质灾害做出合理的预防。本文意在通过噪声成像近年来的研究现状,尤其是浅层结构勘查应用(如城市地下结构、矿产、断层等),介绍噪声成像的发展背景,数据处理特点,综述其在浅层结构勘查方面的应用及可靠性,探讨其技术方法的完善,以获得浅层精细3D或4D结构图。In recent years background noise imaging methods have gradually matured.With the deepening of research theories many scholars have applied them to study of the deep velocity structure of the Earth,and have achieved good results.More shallow physical information obtained in the study of shallow structures will greatly enhance the understanding of shallow structures.The shear wave velocity information obtained by the noise cross-correlation imaging method can effectively identify underground structures with large differences in velocity such as underground faults,voids and caves,which will help us to prevent the geological disasters such as earthquakes.This paper intends to introduce the research status of noise imaging in recent years,especially shallow structure exploration applications(such as urban underground structures,minerals,faults,etc.),introduce the development background of noise imaging,data processing characteristics,and summarize its exploration in shallow structure.Application and reliability,explore the perfection of the technical methods to obtain shallow fine 3 Dor 4 Dstructural drawings.
