A Review of Efficient and Low-Carbon Pile Technologies for Extra-Thick Soft Strata

With the development of urban underground space and increased infrastructure functions, both scale engineering construction difficulties have globally. In structures in soft strata, especially coastal areas, limited bearing capacity foundations poses a significant challenge. The composite pile technologies employing an organic combination rigid andthe flexible column can enable efficient ground treatment. light prominent global environmental issues, low-carbon energy-saving curing been rapidly developed for application geotechnical engineering. This paper discusses progress research on mechanical properties technologies, including stiffened deep mixing (SDM) column, squeezed branch pile, pre-bored grouting plated nodular (PGPN) precast cement reinforced by cemented soil with variable section (PCCV), carbonized (CCP). addition, it reviews technical characteristics recent feasible energy-efficient technologies. also proposes future directions theoretical technological key contribution this review is to provide insights into findings from study used extra-thick strata industry practitioners comprehensive guide regarding specific applications performance which serve as stepping stone facilitate industry.
