近年来,采空区、岩溶、地裂缝、滑坡等地质灾害发生频繁,严重威胁着国家工程建设及人类生命财产,如何选取地球物理探测方法,并快速有效地查明这些地质灾害的空间赋存特征,对于指导地质灾害的治理和施工工程尤为重要。本文首先阐述地震映像方法原理,然后结合一些工程实例的应用,具体分析不同地质灾害所表现出的地球物理异常特征,探讨了地震映像法在探测这些地质灾害的应用效果。结果表明该方法在地质灾害调查方面具有探测分辨率高、经济快速、准确有效等优势,能够弥补其它方法的不足。 In recent years, geological disasters such as mined-out area, karst, ground fissure and landslide occur frequently, which threaten national engineering construction and human life and property seriously. How to select geophysical exploration methods and identify the spatial occurrence of these geological disasters quickly and effectively Features, for guiding geological disaster management and construction projects is particularly important. In this paper, the principle of seismic mapping method is first described. Combined with the application of some engineering examples, the geophysical anomaly characteristics of different geological disasters are analyzed in detail. The application of seismic mapping in detecting these geological disasters is discussed. The results show that this method has the advantages of high detection resolution, rapid economy, accuracy and effectiveness in the investigation of geological disasters and can make up for the deficiencies of other methods.
