川藏公路前龙段滑坡整治工程的锚索抗滑桩设计研究

Research on the Design of Anti-slide piles with anchors in the Landslide Control Engineering in Qianlong Section of Sichuan-Tibet Road

本文依据川藏公路前龙段滑坡机理及整治技术研究成果,对现有锚索抗滑桩设计理论和方法进行了研究,分析了锚索预应力下岩土抗力对抗滑桩受力的影响,引入了锚索拉力系数m的概念,提出了半坡桩设计要点,为改进完善锚索抗滑桩设计提供借鉴。

According to the research conclusion about landslide mechanism and construction technique in Qianlong section along Sichuan-Tibet Road,based on the design theory and method of anchor wire pile,this paper analyzed the effect of the resistance force of the rock and soil under the prestressed anchor on the pile's internal force,introduced the concept of pull coefficient m in the design of anchor wire pile,emphasized the two key points in the design of half-slope pile,which can be used as reference in perfecting the design theory of anti-slide piles with anchors.
