断层滑动分布和位错模型影响效应的显著性分析
ANALYSIS OF INFLUENCES OF FAULT SLIPPING DISTRIBUTION AND DISLOCATION MODEL
摘要
Abstract
The co-seismic displacement caused by Wenchuan earthquake (Ms8.0)was calculated with four seismic slip models using half-space(Okada) and spherical dislocation theory(Shen et al),respectively,and the displacement field calculated and the observation result were compared.Statistical significance caused by fault slipping and dislocation models were analyzed using the method of two-factor variance.Results show that co-seismic displacements calculated by the spherical dislocation model is consistent with the observation results,the mean value of residual is 0.007 m,and its trace is 0.006 m.Near the fault rupture,both slipping factor and dislocation factor causing larger mean square deviation,the maximum is S2A =7.170 16 m2,S2B =91.407 7 m2,respectively.The significant influence of slipping distribution and dislocation model shows the characteristics of different space distribution,the former is embodied in the near field area,while dislocation model is mainly embodied in the far-field region.关键词
