Abstract：Soil compaction in the process of pile driving has always plagued engineers. How to speed up the dissipation of excess pore water pressure during the pile driving is the current research focus. The permeable pipe pile, which is featured by series of drainage hole distributed along the pile shaft, can accelerate the dissipation of excess pore water pressure and the soil consolidation. The effect ofreducing the soil compaction and speeding up the dissipation of excess pore water pressure during the pile driving is inherent in the service of permeable pipe pile, which can improve engineering efficiency and save project cost. The technique of permeable pipe pile, combining the advantage of pile foundation and drainage consolidation method, can apply to pile foundation construction and ground treatment with high economic efficiency. In this paper, a review of recent advances in permeable pipe pile is carried out, and the research results of the bearing performance, permeable performance, and drainage hole distribution optimization of permeable pipe pile are summarized. In the end, brief discussion of the existing problems and the future research direction in permeable pipe pile is conducted.
