In order to meet the needs of capable fault geological survey on nuclear power project sites, this paper proposes a technical method of using common-offset shallow seismic reflection profiles to extend the interpretation depth of geological cross-sections. Through comprehensive interpretation of the physical properties and lithology, the identification of capable faults and determination of their attitude can be more reliable. The test results show that the method is effective and feasible. The fracture zones found on geological profiles are also visible on the common-offset shallow seismic reflection profiles. The geological and seismic interpretations may verify each other. The technical approach provided by this paper can be applied to similar engineering geological investigations, and also to buried fault detection in a thin Quaternary covered area.
