Abstract

Present study dwells with the propagation of quasi seismic qP/qSV waves in highly anisotropic triclinic layer between distinct semi-infinite geomedia. The analytical expressions for reflection/transmission angle and velocity profile of all the propagating waves are derived first followed by formulation of closed form reflection/transmission (RT) coefficients. An application of the present work for underground blast modelling in anisotropic media is discussed. The numerical simulations and visual depiction of the derived results are explored for a specific model; however, the approach is generic and bestow a framework to analysed the seismic signal in similar anisotropic layered structure. The critical angle of reflection/transmission, Energy flux ratio and slowness diagram are drawn. Four published works on reflection/transmission phenomenon with simpler geometry are derived as particular cases to present study.
