In reclamation projects,the construction of containment bund in areas with silt or silty soil often faces technical challenges such as insufficient foundation bearing capacity and slow drainage consolidation,leading to poor stability and difficulties in formation.Traditional methods typically require pre-treatment and reinforcement of the containment bund foundation,which involve issues such as prolonged construction periods,complex processes,and high costs.To effectively solve these problems,a new bamboo-wood truss partition containment bund structural system is studied,specifically designed for water-rich,low-strength silty soil conditions.Through the establishment of a finite element model,a systematic numerical analysis is conducted to evaluate its structural safety,overall stability,and deformation control capabilities under soft foundation conditions.The system is validated by the case studies of the No.9 and No.10 general berths project in Huanghua Port comprehensive port area and the Benin Ahime Lake dredging project.The results demonstrate that the bamboo-wood truss partition containment bund structure significantly enhances overall stability and reduces project costs.In practical applications,this system reduces project costs by approximately 20% compared to traditional methods,while also exhibiting excellent adaptability and environmental performance.This structural system provides an economical,efficient,and reliable solution for reclamation containment bund projects in weak geological environments,holding significant promotional value.
