A New Technology for Low-carbon and Environmentally-friendly Composite Bamboo Pile Foundation Support

Most existing foundation pit support structures are composed of cement and steel, materials characterized by high energy consumption and carbon emissions. Bamboo features high short-term strength, stable mechanical performance, and renewability, making it suitable for temporary support structures in foundation pits. In this study, a composite foundation pit enclosure system was developed, in which bamboo replaces steel soil nails and bamboo mesh substitutes for steel reinforcement in concrete layers. A numerical model of the bamboo composite foundation pit was established to investigate the effects of different support configurations on pit stability.
