抗滑刚架桩挡墙的设计与应用

Design and application of retaining wall with anti-sliding frame piles

摘要: 对于滑面较深、推力较大的滑坡,抗滑刚架桩上设置挡墙会显著地减小抗滑刚架桩长径比,故抗滑刚架桩挡墙将会越来越广泛地应用于滑坡治理工程中。在文克尔弹性地基理论的基础上,本文采用有限差分法推导了抗滑刚架桩挡墙的计算公式。所提出的计算方法已应用于工程实际中,取得了良好效果。还明确了抗滑刚架桩挡墙的适用条件。通过与抗滑刚架桩的对比分析,得出了一些有益的结论,比如在相同的条件下,抗滑刚架桩挡墙的位移约是抗滑刚架桩的55%。

Abstract: To the landslide with deep slip surface and large landslide thrust,anti-sliding frame piles with retaining wall can significantly decrease the aspect ratio of the piles,so retaining wall with anti-sliding frame piles will be applied to the treatment of landslide more and more widely.Based on the theory of Winker elastic foundation,a new calculation method is presented,which can calculate retaining wall with anti-sliding frame piles through finite difference method.The method has been used in pra...
