摘要

The present study deals with the Love wave propagation in a dry sandy layer sandwiched between upper monoclinic elastic layer and lower inhomogeneous isotropic elastic half-space. Rectangular type irregularity is considered at the interface of sandy layer and half-space. Analytical expressions for displacement fields are derived by adopting the variable separation method. Dispersion equation for the phase velocity of Love wave is also derived by using suitable boundary conditions and validation with standard Love wave equation is also verified, discussed in particular case. Significant effect of parameter like sandiness, irregularity, inhomogeneity and thickness ratio is observed by analyzing the dispersion equation graphically using MATLAB software. Results obtained regarding Love wave propagation in the considered model serve as major highlights having significant relevance in the field of geophysics, soil mechanics and earthquake engineering.
