双排桩式导流堤在泥石流治理中应用研究

Research on the Application of Double Row Pile Diversion Embankment in Debris Flow Control

天津市蓟州区西毛峪山谷在2021年发生泥石流,造成国道断交,严重危及公路通行安全。文章在分析泥石流特征的基础上,在泥石流堆积区尝试采用双排桩作为导流堤,形成导流槽治理西毛峪泥石流。文章分析了双排桩式导流堤的受力状态,计算了其稳定性,提出了治理方案,工程取得良好效果。本研究为后续同类泥石流治理提供了参考。

In 2021,a mudslide occurred in Ximaoyu Valley,Jizhou District,Tianjin,causing the national highway to be cut off,and seriously endangering the safety of road traffic.On the basis of analyzing the characteristics of debris flows,this paper attempts to use double row piles as diversion embankments in the debris flow accumulation area to forming diversion channels to control Ximaoyu debris flow.This paper analyzes the stress state of the double row pile diversion embankment,calculates its stability,proposes a treatment plan,and achieves good results in the project.This paper provides a reference for the subsequent treatment of similar debris flows.
