Analytical Solution for One-Dimensional Consolidation of Layered Composite Foundations With Partially Penetrated Impervious Piles Under Multi-Stage Loading
This study investigates the consolidation behavior of layered foundations reinforced by partially penetrating impervious piles. The analytical solution of a layered composite foundation reinforced by partially penetrated impervious piles is derived by considering the assumption of vertical equal strain and multi-stage loading. The accuracy of the proposed analytical solution is confirmed through comparison with both a known special case solution and finite element method (FEM) simulation results. A comprehensive set of parametric studies is also performed using the derived analytical solution. The findings reveal that the application of multi-stage loading contributes to minimizing the build-up of excess pore water pressure (EPWP), while simultaneously decelerating the consolidation rate in composite foundation systems. Ignoring the underlying layer will overestimate the reinforcement effect of impervious piles on layered composite foundations.
期刊介绍：
The journal welcomes manuscripts that substantially contribute to the understanding of the complex mechanical behaviour of geomaterials (soils, rocks, concrete, ice, snow, and powders), through innovative experimental techniques, and/or through the development of novel numerical or hybrid experimental/numerical modelling concepts in geomechanics. Topics of interest include instabilities and localization, interface and surface phenomena, fracture and failure, multi-physics and other time-dependent phenomena, micromechanics and multi-scale methods, and inverse analysis and stochastic methods. Papers related to energy and environmental issues are particularly welcome. The illustration of the proposed methods and techniques to engineering problems is encouraged. However, manuscripts dealing with applications of existing methods, or proposing incremental improvements to existing methods – in particular marginal extensions of existing analytical solutions or numerical methods – will not be considered for review.
