【摘要】 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。更多还原

【Abstract】 In recent years,the geological disaster such as the goaf,karst,fractures and landslides happened frequently,which severely threats the engineering construction and human life.How to take the effective exploration methods and to find out the space features of geological disaster are very important to control geological disaster.The principle of seismic imaging method is formulated.Through some engineering examples,the features of the geophysical abnormity of the geological disaster are analyzed,and the effect of the method to detect the geological disaster is discussed.The results indicate that the said method is of the advantages such as high resolution,low cost,fast and accuracy in geological disaster investigation,which could make up the shortcoming for other methods.更多还原
