TL;DR: In this paper, the torsional dynamic response of an end bearing pile embedded in radially inhomogeneous saturated soil is analyzed using Biot's two-phase linear theory and its radial inhomogeneity due to the construction disturbance effect is considered by radially gradual variation of soil parameters.

TL;DR: In this paper, a closed-form series solution was developed to analyze the vertical vibration of a circular cross-section pile embedded in radially disturbed soil, which was then employed to investigate the effect of degree of disturbance and extent, and the pile length and elastic modulus on the vertical impedance of pile.

TL;DR: In this paper, the vertical vibration characteristics of an end bearing pile interacting with the saturated soil that is of distinctly inhomogeneous behavior in the radial direction due to the construction disturbance were investigated.

TL;DR: In this paper, a new analytical model for calculating the horizontal dynamic impedance of pile groups with arbitrary members connected with a rigid pile cap is presented, which allows robustly the effect of pile-to-pile interaction on the impedance of the group, by accounting for the secondary waves generated by the vibration of the receiver pile, and how these alter the response of the source pile.

TL;DR: In this paper , the authors investigated the effect of construction disturbance on the horizontal dynamic response of pile embedded in unsaturated soil when the pile is subjected to time-harmonic horizontal loading and vertical loading.

TL;DR: In this paper, a homogenization equation is proposed for the small strain stiffness of gap-graded granular soils to reproduce the small-strain stiffness observed in numerical simulations and further validated by laboratory test data from the literature.

TL;DR: Both the DLSITs and PSTs suffer obvious high frequency interference arisen from the 3D effect of piles and the radius angle between the impact force location and the axial line of receiving sensors is advised to set as 90°.
