Effect of Hydrological Properties on the Energy Shares of Reflected Waves at the Surface of a Partially Saturated Porous Solid

摘要: In the present study, reflection of inhomogeneous waves is investigated at stress-free plane surface based on multiphase poroelasticity theory. The porous medium considered as dissipative due to presence viscosity in pores fluid. Four (i.e. different direction propagation and attenuation) reflected (three longitudinal one shear) exists an incident wave. By using appropriate boundary conditions, closed-form analytical expressions for coeffcients are derived surface. These used drive energy shares various waves. mathematical framework, conservation confirmed by considering interaction between two dissimilar It validates that numerical calculations analytically correct. Finally, a example study effects viscous cross-coupling, porosity, saturation gas, pore-characteristics wave frequency depicted graphically.
