APPLICATION OF SEISMIC MAPPING EXPLORATION IN SEISMIC SAFETY EVALUATION OF ENGINEERING SITES

At site work of seismic safety evaluation in Quaternary System coverage area, active fault detection is an important work.When the depth of target layer is at several tens meter, seismic mapping exploration is an effective measure to detect active fault.The application in the site of Tangshan North Suburb Thermoelectric Plant and Guyuan Power Plant shows that its effect is notable.
