Abstract
The rapid mobilization of the capacity of precast-driven piles is closely tied to the consolidation of the surrounding soil. Permeable pipe piles, which function as both load-bearing foundations and drainage pathways, offer the advantage of quick capacity mobilization. However, the absence of a time-dependent theory for permeable pipe pile–soil interaction significantly limits the advancement and widespread application of this innovative pile technology. This study proposes a numerical framework to analyze soil consolidation and skin friction development along the shaft of permeable pipe piles. The framework is validated through comparisons with simplified theoretical solutions and experimental results. A parametric analysis is conducted to elucidate the capacity mobilization process, providing guidance for optimizing the design of permeable pipe piles.
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.
