    Wave propagation in the soil plays a crucial role in problems of rail or road traffic induced vibrations in buildings as it couples the source (the road or the track) and the receiver (the building).Numerical mod-els aiming to predict traffic induced vibration should therefore account for dynamic soil-structure interac-. As there is no analytical solution for the 2D wave propagation in unsaturated soils in the literature, to verify the accuracy of this implementation, the displacement response obtained by the boundary element formulation is partially verified by comparison with the elastodynamics problem.

    Utilizing the developed solution, a parametric study is performed to illustrate the influence of the properties of the soil–pile system on the vertical dynamic response of the pipe pile. Finally, the validity of the additional mass model is validated by conducting a set of model tests, based on which the concept of “apparent wave velocity.   An effort is made in this state‐of‐the‐art paper to present a representative sample of the experimentally observed rheologic response characteristics of cohesionless soils subjected to dynamic loadings, both with and without inertial effects, and to evaluate the usefulness of various idealized continuum and particulate theories for describing this response.

    This article reviews recent developments in the interaction between water waves, seabed, and coastal structures. The scope of the review covers theoretical approaches and physical modeling for the wave-induced soil response, wave damping, and sea floor instability around coastal structures. Understanding the dynamic wave signatures in near surface unsaturated soils is crucial for the application of seismic observations in hydrology. We first derived and analyzed the half-space spatiotemporal Green's functions that correspond to the raw seismic recordings, incorporating fluid, pressure jump and free surface boundary conditions represented by the surface stiffness.

(ed.). The main scientific and engineering goal of this book is to deal simultaneously with soil dynamics/vibrations and wave propagation in soils (including seismic waves). These various fields are generally considered separately and the important links between them, both from scientific and practical points of view, are unfortunately not investigated.

In this paper, shear wave propagation in soils is examined in a stochastic context considering spatial variability of the shear modulus soil parameter.

To this purpose, the recently established concept of dynamic mean and variability response functions (DMRF, DVRF) is reformulated in the framework of stochastic finite element analyses of shear.

To study the vibration propagation rules of the roller, the vibration acceleration of the high-power vibrating roller was measured on the surface of the rock subgrade, coarse-grained soil subgrade and. Propagation of Compressional and Shear Waves.

The effect of soil viscosity on the wave speeds of P1, P2, and S waves in the frequency range below 30 Hz is depicted in Figure saturation degree is % and the damping coefficient is taken to be 0,andrespectively.

The wave speeds of P1, P2, and S waves increase with the increase of viscosity, while the influence of soil. Visco-hypoplastic constitutive models reproduce properly the non-linear soil dynamic behavior, carrying effective stress analysis out. That is, viscohypoplastic models can simulate pore pressure build up, stiffness degradation, permanent deformation, non-linear viscous effects (time and rate dependence) and some non-linear effects observed in the wave propagation in undrained soft soils.

In recent decades, the blast load impact on structures has acquired considerable attention due to magnified threats from various man-made activities. Understanding the shock wave propagation in soil and its interaction with structure are crucial in a blast scenario. In a surface or sub-surface blast, the shock wave mechanics and its subsequent impact on underground or above ground structures.

The response of soils to cyclic loading is controlled mostly by the mechanical properties of the soil. There are several types of geotechnical engineering problems associated with dynamic loading, some examples include: wave propagation, machine vibrations, seismic loading, liquefaction and cyclic transient loading, etc.

The mechanical.particles move in the direction of wave propagation. For S-waves, transversal or shear waves, the soil particles move perpendicular to the direction of wave propagation. The S-waves can be further divided into components in a horizontal plane, named as SH-waves, and in.
