Propagation of Rayleigh waves in fluid‐saturated non‐homogeneous soils with the graded solid skeleton distribution

Abstract: Summary The propagation characteristic of Rayleigh waves in a fluid‐saturated non‐homogeneous poroelastic half‐plane is addressed. Based on Biot's theory for fluid‐saturated media, which takes the inertia, fluid viscosity, mechanical coupling, compressibility of solid grains, and fluid into account, the dispersion equations of Rayleigh waves in fluid‐saturated non‐homogeneous soils/rocks are established. By considering the shear modulus of solid skeleton variation with depth exponentially, a small parameter, w… Show more

“…In recent years, to further explore the influence mechanism of Rayleigh waves on engineering structures, scholars have paid more and more attention on the propagation characteristics and attenuation of Rayleigh waves by using elastic wave theory. According to the types of propagation media, most of research results related to the horizontal dynamic response of the soil medium under Rayleigh waves can be summarized as propagation theory of Rayleigh waves in single‐phase media, saturated porous media and three‐phase porous media 1,2,10,11 . However, the influence of Rayleigh waves on the dynamic response of a soil–pile system is seldom referred.…”

“…Therefore, the model developed by Biot laid the foundation for the dynamic analysis in biphase or even multiphase porous media. Since then, based on the Biot model, many researchers [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] carried out various related works on the propagation of elastic waves in saturated porous media.…”

“…Undoubtedly, the emergence of Biot theory [3,4] and mixture theory [5] not only give the sound basis for the research of wave theory but accelerate the research process. For the bulk and Rayleigh waves propagation in saturated soil, researchers including Jones [6], Plona [7], Berryman [1], Berryman [8,9], Zhou and Ma [10], Straughan et al [11], Rohan et al [12], Tung [13], and Wang et al [14] implemented several theoretical and experimental works. They drew that the longitudinal, transverse, and Rayleigh waves depend on not only the frequency but the soil parameters such as permeability and soil mass types.…”
