DETERMINING OF SEISMIC DESIGN PARAMETERS FOR DALIAN DEVELOPING AREA AND NEW HARBOUR AREA

After delimiting potential earthquake sources in a working area, determining of seismicity parameters in potential earthquake sources, and from attenuation relation of ground motion, we have made an analysis of seismic risk for both these eraeas. We abtained earthquake intensity of different probability and horizontal peak accleration at the bed rock as well as response spectrum. From the statistics of earthquake intensity attenuation a basic intensity of the sites was obtaimed. Based on the engineering seismologcal conditions we have classified geological units and types of sites, calculated seismic response of different probability, and determined ground motion parameters for design.
