| 摘 要： | 本文介绍了地球化学探测方法作为控制性探测隐伏断层的有效手段,在厦门城市隐伏断层的探测中得到了充分的应用。通过地球化学试验探测,可确定地球化学探测的异常下限值,同时在采取了一系列质量保障措施后,增强了判断异常点的可靠性,研究表明地球化学探测异常点呈明显的线性分布。经浅层地震探测验证,地球化学探测解译的断层分布位置与浅层地震探测断点吻合程度较高,表明该方法用于城市隐伏断层探测是有效可行的。

| Abstract: | The geochemistry survey has been approved to be a effective method for locating blind fault.In the project of urban active fault survey and earthquake risk evaluation of Xiamen city,we carried out a experimental geochemistry survey to determine the lower limit of abnormal value,and strengthen the abnormal reliability through taking a series of quality safeguard mechanism.The survey result shows a linear trend line composed with abnormal sites.The interpretation of fault branching location from geochemistry ... |
