Numerical Analysis of Soil Consolidation and Time‐Dependent Skin Friction Mobilization Around Permeable Pipe Pile

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.
