抗滑桩在合福客专兹坞坑滑坡治理中的应用

摘要

In DK438 +755 ~ +880 Section of Hefei-Fuzhou PDL, the toe of Ziwukeng Landslide is bridged over. For the purpose of safety, anti-sliding piles are used for the treatment to the extent that the landslide thrust is obtained by transfer coefficient method and the proper pile length specified by force analysis. Currently, the anti-sliding piles have been completed. The monitoring indicates that the displacement of pile top is satisfied and the landslide is stable in rainy season. The fact proves the anti-sliding piles to be safe and reliable in the treatment of Ziwukeng Landslide for Hefei-Fuzhou PDL.%合肥至福州铁路客运专线DK438+ 755～+880段,以桥梁跨越兹坞坑滑坡前缘.为确保工程安全,对滑坡采用抗滑桩进行整治.采用传递系数法获得滑坡推力,通过受力分析确定了合理的桩长.目前,抗滑桩已施工完毕.监测结果表明抗滑桩桩顶位移满足规范要求；而滑坡体在雨季保持稳定.事实证明,抗滑桩在合福客专兹坞坑滑坡的治理中安全、可靠.
