松散覆盖层内隐伏断层探测研究
|
摘要
为了确定大城市松散覆盖层内隐伏断层的性质及其活动性,采用地震反射勘探方法及通过深浅结合的方式,探测了几十米至2km范围内的隐伏断裂构造,确定了断裂的性质及深浅构造之间的关系;并通过两条断层探测的实例,分析了覆盖层内隐伏断层的某些特征,提出了浅、中、深相结合的探测方法。
For acquiring the properties and activity of the buried fault under the loose overburden in some large cities,the faults in depth from tens metres to two kilometers have been explorated by use of reflection-seismic prospecting method and combining the data in deep and shallow strata and the properties of the faults and the relations between deep faults and shallow faults are determined.Some characteristics of the buried faults under overburden are analyzed through two examples of prospecting faults.A method combining shallow,middle and deep seismic prospecting of exploring the buried faults is put forward.
