随着抗滑桩应用的日益广泛，利用单桩承载力或是通过经验进行抗滑桩间距估计的方法已经不能满足抗滑桩设计的安全和经济需求。而在桩土相互作用过程中，土拱效应往往起着极其重要的作用。鉴于土拱效应对于抗滑桩间距计算的重要性，对基于土拱效应的抗滑桩间距计算方法进行了总结。分别根据静力平衡条件，大小主应力理论和土拱强度条件，介绍了三大类不同计算方法，并分析了各自主要特点，由此提出了今后利用土拱效应计算合理桩间距时应注意的问题及相关建议。

With the wild application of friction pile, the method of using single pile to bear stress or estimating friction pile distance cannot meet the safe-ty and economic requirements of friction design. In the interaction process of pile and soil, soil arch effect plays a very important role. In view of the im-portance of soil arch effect to friction pile distance calculation, the calculation methods of friction pile distance are summarized. Based on the static bal-ance condition, principle stress theory and soil arch strength condition, three kinds of calculation methods are introduced with their main features ana-lyzed. Thus, relevant problems and suggestions are presented.
