渭河断裂窖店浅层地震与钻孔联合剖面研究
|
摘要
为确定渭河断裂中部隐伏段的位置,在咸阳窑店布设了浅层地震勘探测线,在浅层地震勘探资料对断层解译的基础上,进一步开展了窑店和陈家沟钻孔联合剖面勘探工作,详细查明了渭河断裂的精确位置和组合特征,结合钻孔土样光释光(OSL)年龄测试和区域地层资料,深入研究了渭河断裂带最新活动年代和滑动速率等特征。
In order to determine the location of underlying part in Weihe fault,shallow seismic surveys profiles were conducted in Yaodian village of Xianyang city.On the base of interpreting the data to Weihe fault,infurthely we finished drilling combined sections in Yaodian and Chenjiagou village.The accurate loction and combined characteristics of Weihe fault was surveyed.With drilling section soil OSL time measures and region layer data,The paper researches the latest active time and slip speed characteristics of the Weihe fault.
