NUMERICAL MODELLING WITH 2.5 D WAVE FIELD IN ANISOTROPIC MEDIA CONTAINING CRACKS

Niu Binhua (Central South University of Techonology , Changsha 410083)Sun Cunyan (Changchun Institute of Earth Sciences, Changchun 130026)  
Studying seismic wave propagation in anisotropic media is an important content in survey geophysics. At first, 2.5D elastic equation is discussed. Then, the finite element method is used for synthetic in 2.5D space anisotropic media containing cracks. The results are showed by time snapshot. Finally. synthetic results are analyzed and discussed. This studied method of synthetic field can be also used to other anisotropic media.
