Based on the relationship,strain-displacement and constitution law,of elastic stress-strain,along with motion balance equation,the transport equations in 2-D and 3-D transversely isotropio medut ore derived using coordinate transformation and SVD (Singular Value Decomposition) technique . By utilizing the derived equation, the problem on the generation of seismic wave thru the shearingly distributed body forces in 2-D transversely isotropic media Is examined. As a result,it reveals that the approach recommended in this paper with respect to the Lamb's problem is much easier and efficient as compared with the conventional methods.
