深大基坑支护体系与环保节能协同关键技术研究OA

In response to the difficulties in coordinating safety,environmental disturbance,and energy consumption in deep and large foundation pit support,this article proposes a collaborative technology framework for support systems and environmental protection and energy saving.Centered on the'two walls in one'underground diaphragm wall,recyclable prestressed steel supports,precise groundwater drawdown and recharge,and digital twin management and control,it establishes a full-process pathway covering design,construction,monitoring,and dismantling/reuse.The results show that this system can reduce material redundancy and demolition waste while ensuring controlled deformation.Precise groundwater drawdown and recharge,slurry purification and reuse,and intelligent scheduling significantly reduce environmental disturbance and energy consumption.Digital twin prediction enhances the efficiency of anomaly detection.This solution has comprehensive advantages in safety,environmental protection,energy saving,and economics,making it suitable for promoting green and intelligent construction of deep and large foundation pits in complex urban environments.
