摘要
现阶段抗滑桩在公路、铁路边坡抗滑工程的应用越来越多。为了获取双排小孔径抗滑桩排间距对桩身破坏特征的影响,评价双排小孔径抗滑桩的安全性,对双排小孔径抗滑桩的排间距进行分析和研究。通过对通平高速公路某边坡双排小孔径抗滑桩施工后的监测、室内比例模型试验和有限元软件模拟,得到此类抗滑桩的受力分配和破坏形式,进而分析排间距对双排小孔径抗滑桩破坏桩顶位移的影响。通过有限元软件对不同排间距进行抗滑桩破坏模拟,发现排间距对双排小孔径抗滑桩存在的影响关系,从而提出合理的桩间距建议,为以后此类工程选用合理的桩间距提供了依据和参考。
The small diameter double-row anti-slide piles,which reinforce the slope in highway and railway engineering,were applied more and more nowadays. In order to figure out the influence of spacing on the pile failure mechanism and evaluate its safety condition,we mainly focus on spacing between piles. By monitoring soil pressure,and scaling down physical models simulated by finite element method of small diameter double-row anti-slide pile in Tongping Highway,the stress distribution and failure mechanism can be found. Also the influence of spacing on small diameter double-row anti-slide pile can be figured out. Applicable spacing between the piles can be concluded which provide reasonable reference for further engineering implementation.
