浅谈设有冠梁的梅花形双排抗滑桩在欠稳定边坡中的应用

On the Application of Plum-shaped Double-row Anti-slide Piles with Crown Beams in Under-stable Slopes

研究发现常规的矩形抗滑桩人工成孔施工过程风险大,单排圆形抗滑桩又不能满足抗滑要求。基于此,本文以S11泾源(甘宁界)至华亭高速公路工程欠稳定边坡加固设计为例,将设有冠梁的梅花形双排抗滑桩作为加固方案,同时根据典型断面采用madis软件建模分析抗滑桩的应力应变、位移及内力分布情况。结果表明抗滑桩在最不利工况条件下桩顶位移满足规范要求。

Taking the unstable slope reinforcement design of the S11 Jingyuan(Gan-ning boundary)-Huating highway project as an example,the conventional rectangular anti-slide piles are relatively risky in the artificial hole construction process,and the single-row circular anti-slide piles cannot meet the anti-slide requirement.Therefore,the quincunx double-row anti-slide piles with crown beams are used as the reinforcement plan.Meanwhile,the madis software is used to model and analyze the stress,strain,displacement and internal force distribution of the anti-slide piles according to the typical section.
