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。
At this stage anti-slide piles in highway, railway slope anti-skid project more and more applications. In order to obtain the effect of double-row small-aperture anti-slide piles on the failure characteristics of piles, the safety of double-row small-aperture anti-slide piles was evaluated and the row spacing of double-row small-aperture anti-slide piles was analyzed and studied. Through the monitoring of double-row small-diameter anti-slide piles on a slope of Tongping Expressway, the indoor scale model test and finite element software simulation, the force distribution and failure modes of such anti-slide piles are obtained, Influence of Double Row Aperture Anti - slide Piles on Top Displacement of Pile. Finite element software was used to simulate the anti-slide pile failure at different row spacing, and the influence of row spacing on the existence of double-row small-aperture anti-slide pile was found out. Then a reasonable proposal of pile spacing was proposed to provide reasonable pile spacing for such projects The basis and reference.
