| 摘 要： | 以银川活动断层试验探测为例,介绍了第四纪巨厚沉积区隐伏断层多手段、多层次探测的步骤与方法。在对前人资料综合分析的基础上,选择银川市兴庆区新渠梢村为综合探测试验场。首先,分层次布施道间距10m、5m和1m的浅层人工地震勘探,由深至浅将银川隐伏断层主断层逐步控制在可以布施浅钻勘探的程度。然后,实施钻孔联合剖面探测,确定了断层的准确位置和倾角,获得了由钻探资料可分辨的断层上断点埋深8.3m的信息。最后,通过大型探槽开挖,查明了断层实际上断点埋深1.5m和5期古地震活动事件。结合地层年龄的初步测定,得出了银川隐伏断层主断层中—晚全新世活动的结论

| Abstract: | Yinchuan Basin is a graben-like downfaulted Cenozoic era basin located on the west edge of Ordos Massif.Its activity is violent and deposition is very thick.Yinchuan City is located in the middle of Yinchuan Basin.The seismic petroleum exploration shows that a buried active fault lies in the east of Yinchuan City,named as the Yinchuan buried fault,which strikes NNE and dips west,with a total length of more than 80km.Because the seismic petroleum exploration did not gain any explained signals at the depth ra |
