Ground Motion Response of Bi-Material Half Space Including Multiple Circular Holes Under Sh Waves Incidence
The ground motion response of the bi-material half space including multiple circular elastic holes impacted by SH waves is investigated. Green’s function approach and the "conjunction" technique of the bi-material interface are applied to derive the Fredholm integral equations of the first kind. Also the method of "image" is mentioned to construct the expressions of equivalent wave field. The expression of amplitude of ground surface displacement is obtained. Numerical computations are performed for a specific model of two circular holes in bi-material half space. The effect of the defects of medium on the amplitude of ground surface displacement is presented graphically.
