ESTIMATION METHODS OF GROUND MOTIONS OF SCENARIO EARTHQUAKE BASED ON BASIN EFFECTS:TAKING BEIJING AS AN EXAMPLE
CHEN Chun-mei;REN Xue-mei;Earthquake Administration of Ningxia Hui Autonomous Region;
By using calculating results of basin amplifications of preceding studying, the ground motions through amplifications of surface soil and basin of scenario earthquake are calculated based on methods of certain seismic hazard analysis. These results and those ground motions of seismic zonation is contrasted, It is found that the basin effects on the ground motions of these scenario earthquakes are great. Basin effects must be considered in the integrated defense and seismic safety of big city in China.
