浅地震反射剖面揭示地震小区划覆盖层厚度及隐伏断裂——以九江芳兰规划区为例
|
摘要
以九江芳兰规划区为例,利用浅层地震反射方法获取小区划工区的覆盖层厚度,并查明周边隐伏断裂位置及特征。结合钻孔资料对比解译,对地震小区划工作提供基础地震地质信息,同时为该区的活断层探测和地震危险性评价提供参考资料。
In this paper,taking the planning area of Jiujiang Fanglan as an example,the thickness of overburden and the location and characteristics of surrounding concealed faults are obtained by means of shallow seismic reflection method.Seismic reflection profiles combined with borehole data interpretation provide abundant seismic and geological information for seismic zoning,and provide reference data for active fault detection and seismic risk assessment in this area.
