震电综合物探方法在滁州市隐伏断裂中的应用
|
摘要
城市的隐伏活动断裂给人口密集的城市带来很大的灾难,所以必须对断裂地带做出准确定位以避开这些区域。利用震电综合物探方法探测城市隐伏活动断裂,以避免采用单一方法在深度、广度、精度方面的不足。地震反射波法不但有利于在干扰背景较强的条件下利用多次覆盖技术压制干扰、提高资料的信噪比,而且利用地震反射剖面上丰富的的反射地震响应也有助于判定断裂的存在与形态。本文以滁州市小区划场地的水泥厂-南营房断裂为例,对隐伏断裂探测所采用的以浅层地震反射波法为主进行深入的研究,并用高密度电阻率法对其进行对比验证。实践表明,采用浅层地震反射波法探测城市隐伏断裂是有效可行的。
Buried active faults to the city's densely populated cities bring great disaster, it is necessary to make accurate positioning on the fracture zone to avoid these areas. The use of electric shock Integrated Geophysical Method city buried active fault detection, in order to avoid the use of a single method in the depth, breadth, accuracy deficiency. The seismic reflection method is not only conducive to the use of multiple coverage technology to suppress interference and improve data signal-to-noise ratio in the conditions of strong interfering background, and the use of seismic reflection profiles on the reflection seismic response also helps to determine the presence of fracture forms. The article take Chuzhou City Microzonation venue cement plant- South barracks fracture as an example, in-depth study on the buried fault detection used in shallow seismic reflection method based depth study, and high-density resistivity method to compare them verification. The practice shows that the city buried fault detection using shallow seismic reflection method is effective and feasible.
