塑料排水板加超载预压在堤防软基的应用

Discussion on the Application of Plastic Drainage Board and Overload Preloading in Soft Foundation of Embankment

通过将塑料排水板打入到软基中,在上部施加荷载,塑料排水板滤膜外侧孔隙水,由板芯排水通道排到上部铺垫的砂层中,形成排水通道,加速软基排水固结,提高基础承载力。结合工程实践,简要介绍其在堤防软基处理中的应用。

By driving the plastic drainage board into the soft base and applying a load on the upper part,the pore water on the outside of the plastic drainage board filter membrane is discharged from the core drainage channel to the upper bedding sand layer to form a drainage channel.It can accelerate the drainage consolidation of the soft foundation and improve the bearing capacity of the foundation.Combined with engineering practice,this paper briefly introduces its application in embankment soft foundation treatment.
