- Abstract:
-
Based on a large number of strong motion data recorded by Jiangsu Province strong motion network since 2006 and the near field distance saturated empirical acceleration attenuation model,we use multiple random variables regression analysis method and least squares fitting to determine the empirical attenuation relation model of each coefficient,and thus the attenuation relationship of ground motion parameters of small and medium earthquakes in Jiangsu and its adjacent areas is obtained.Take the July 20,2012 Jiangsu Gaoyou M4.9 earthquake as an example,we calculated its ground acceleration field in the focal region combined with the new the attenuation relation.The results show that compared to use the results of direct interpolation method,the attenuation relationship between the corrected results the vibration acceleration field of continuous distribution features are more obvious,and more close to the actual investigation to the seismic intensity distribution.
