摘　　要：为研究青山口-黄陂断裂的活动性,采用XG-4型数字测汞仪和甚低频测量仪对横跨该断裂的4条测线进行了壤中气汞及电磁场同步测量。测量数据显示,在断裂活动性较强地段,断裂所在部位的壤中气汞异常值和电磁场异常值较高;在活动性较弱地段,断裂所在部位的壤中气汞异常值和电磁场异常值较低。这表明壤中气汞及电磁场同步测量不但可以用来确定断层的位置,而且还可以用来研究断层的活动性。According to the requirements of the project, we undertook research on the activity of Qingshankou Huangpi Fault. In this study, we measured gaseous mercury in soil and electromagnetic field along 4 lines accrosing the Fault by XG4 digital mercury analyzer and very low frequency analyzer. The measure data indicate that conte nents of intensity of gaseous mercury in soil and electromagnetic is closely related to fault activity. In the active sec tions of the fault, abnormality of gaseous mercury in soil and electromagnetic field are much higher than that in the stable sections. The results mean that the two methods above can be used not only to confirm the location of faults, but also can be used to analize intensity of an active fault.
