摘要
抗滑桩后土拱性质的研究对设桩尺寸和间距有着极为重要的意义,之前的研究多建立结构力学计算的基础上,与实际情况有很大出入.运用FLAC3D软件对桩后土拱效应进行了数值模拟,并对土拱形成后的作用范围,以及土体性质、桩截面、桩间距等因素对其作用范围的影响进行了初步探讨,在桩后土拱的存在形式及相关因素等问题上,提出了与以往的观点不同的看法和认识.在对桩后土拱的几何尺寸进行定性和定量描述的基础上,初步探讨了各因素对土拱作用范围的影响以及影响程度等问题,对进一步深入研究桩后土拱的性质(包括拱的作用范围以及临界状态等)有一定的参考价值.
The research on the property of soil arch behind anti-slide piles is very meaningful for pile designing and the assuming of distance between piles; but researches on the topic before were based on calculations of structural mechanics, so there were difference between the theories and practile. In this article, numerical analysis was used to simulate the soil arch with FLAC-3D; and the affecting scope of soil arch, the effect of the property of soil, the section of pile, and the distance between piles, etc. , are discussed. On the problem of the form and affect factors of soil arch, the writers offer a new outlook. Based on the qualitative and quantitative description, the writers discussed the effect of these factors and the degree of their effect; and this article gives a reference to further research.
