摘要

本文介绍了自１９８６年以来用汞探测隐伏断层性状及在工程地震应用中的部分结果。通过研究这些结果作者认为，用土壤中气汞可以准确地确定隐伏断层的位置；而根据土壤中气汞和土汞的异常特征确定隐伏断层的倾向也是有效的。这些结论被浅层物探、石油地震勘探及探槽等资料所证实。文中还从实际资料出发，对用汞来确定隐伏断层的性状、断层顶端的埋深及其活动性分段及汞异常特征的机理进行了初步讨论。
This paper deals with a part of results that mercury has been applied to survey the characters of the buried faults and used in seismic engineerings since 1986. It is suggested that locations of buried faults can be accurately determined by using the gaseous mercury in soil, and dips of buried faults can be effectively determined based on the anomalous features of the gaseous mercury and soil mercury. The detected results have been proved by the data of shallow geophysical exploration, petroleum seismic exploration and trenches,etc.Determining the characters, buried depths of apices and activity segmentation of the buried faults by marking use of mercury as well as mechanism of the anomalous characteristics of mercury are discussed preliminarily in this paper on the basis of the practical data.
