【摘要】 现有基坑支护结构大都由高耗能、高排放的水泥和钢材构成。毛竹具有短期强度大、性能稳定、可再生等优点，符合基坑临时支护结构的需要。以毛竹取代钢质土钉，层砼中用竹篾网取代钢筋网构成复合基坑围护结构，建立了毛竹复合基坑数值模型，研究了不同支护方案对基坑稳定性的影响。更多还原

【Abstract】 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.更多还原
