Abstract: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 reflectionseismic 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.
