摘要

为验证沉埋桩加固滑坡体的作用机制，在进行了系列室内大型模拟试验的基础上，对模型试验进行了数值分析。分析中采用有限元方法，计算了桩身所受推力分布型式、推力大小和桩顶土推力分布形式、大小；计算了桩长变化时滑坡体加固后的稳定安全系数，由此确定满足设计要求的最小沉埋桩桩长。研究表明，有限元数值分析方法计算所得到的结果与模型试验的结果比较接近，并证明了用有限元数值分析方法对沉埋桩进行设计的可行性。

Abstract

In order to testify the mechanism of deeply buried anti-slide piles to reinforce the slope

the finite element method is used to analyze the experiment

the distribution and magnitude of lateral force on the piles and the distribution and magnitude of lateral force on the top of the pile are computed

and the safe coefficient varying with pile length from which the least length of deeply buried anti-slide piles meeting the needs of design is acquired. It shows that the result calculated by the finite element method is close to that got from the experiment. It proves the feasibility of designing the deeply buried anti-slide piles by the finite element method.
