Abstract
ABSTRACT An analysis is developed for torsional dynamics of end-bearing pile foundations embedded in inhomogeneous soil deposits. The inhomogeneity of the soil deposit is incorporated in the analysis through an algebraic expression that can simulate linear, parabolic, and hyperbolic variation of shear modulus with depth. In the analysis, the pile is modelled as a one-dimensional elastic continuum, while the soil is a three-dimensional viscoelastic continuum. The Extended Hamilton’s Principle is employed to derive the governing differential equations describing pile and soil motions, which are solved employing Bessel functions and Ritz procedure, respectively. The accuracy of the analysis is verified against existing solutions in the literature. The proposed framework is further employed to study the influence of inhomogeneity. From the study, it is found that the effect of soil inhomogeneity on dynamic torsional stiffness, wave propagation, and pile-twist distribution cannot be neglected, especially for softer (pile-soil stiffness ratio greater than 500) soil deposits.
This paper demonstrates a new analytical formulation for axially loaded end-bearing pile foundations embedded in a nonhomogeneous soil deposit. The nonhomogeneity in the analysis is introduced through an analytical expression that describes parabolic, linear, and hyperbolic variations of the shear modulus with depth....

An analytical model is proposed to investigate the kinematic response of a single endbearing pile in partially treated soil under vertical P-waves. Region-matching method is adopted to divide the physical domain of the soil-pile system into three parts. The total vertical displacement of the system is assumed to be the...

Energy piles are analyzed using the load‐transfer method or numerical methods. While the equivalent soil spring‐based load‐transfer method is fast and easy to use, the equivalent soil spring constants often incorporate empiricism in the analysis. In contrast, numerical methods are more accurate and represent the pile...

A fundamental problem in theoretical soil mechanics, and one with an interesting history, involves determining the lateral force per unit length required to translate a rigid circular pile (or other cylindrical object) through a body of rigid–plastic cohesive soil. A dimensionless factor α is typically used to specify...
Due to natural sedimentary consolidation processes or the directional arrangement of soil particles, foundation soils often exhibit cross-anisotropic characteristics. To investigate the coupled dynamic behavior of a pile-soil system in saturated cross-anisotropic soil under vertical seismic P-waves, this study establis...
