Abstract: In this paper, the hollow anti-sliding pile is brought forward as a new structural form in single anti-sliding pile field. By the finite element analysis, the stress and displacement of the piles are got on the basis of satisfying the structural request. It is gratified that concrete and steel can be quite saved in the design by using the hollow anti-sliding pile. In consequence, using the new form of piles is economic and cost-effective .

Key words: hollow anti-sliding piles, capability of mechanics, evaluation of economy, finite element analysis

摘要： 笔者针对单根的抗滑桩，对空心截面和实心截面抗滑桩进行了力学性能的对比分析，对空心截面抗滑桩的钢 筋用量进行了经济评价．并通过对桩一边坡的有限元模拟分析，得出空心截面抗滑桩不仅能满足抗滑结构要求，而 且节省材料是一种较为经济的截面形式，为今后空心截面抗滑桩的设计提供一种新的思路．
