This study investigates the propagation characteristics of Rayleigh waves in partially saturated poroviscoelastic half-spaces based on fundamental theories of elastic wave propagation. Firstly, a poroviscoelastic model tailored to unsaturated porous media is developed, integrating constitutive relations and dynamic equilibrium equations with fractional derivatives to effectively capture the complex, history-dependent viscoelastic behavior of materials. Secondly, the potential function method is employed to derive the dispersion equation for Rayleigh waves in the proposed medium. Lastly, numerical simulations are conducted to analyze the effects of liquid saturation and fractional order parameters on Rayleigh wave velocity, with results presented through graphical illustrations. The analysis reveals that both liquid saturation and fractional order significantly influence the propagation features of Rayleigh waves. This work provides valuable theoretical support for seismic exploration and related engineering applications involving unsaturated porous formations. [ABSTRACT FROM AUTHOR] |
