通过FLAC-3D程序对桩后的土拱效应进行数值模拟,并对抗滑桩间土拱的存在形式及影响因素进行了初步的探讨,提出了与以往的观点不同的新的看法和认识,更加全面地对桩后土拱的几何尺寸进行了定性和定量的描述,对进一步认识桩间土拱的物理和力学的性质具有一定的参考价值。文章大致分为两部分,首先对桩间土拱的尺寸进行了研究,初步分析了桩间土拱的存在形式;然后又对影响土拱高度的因素进行了一定深度的探讨。
Through the FLAC-3D program, the soil arching effect after the pile is numerically simulated and the existing forms and influencing factors of soil arching between the anti-slide piles are discussed. Some new opinions and understandings different from the previous ones are put forward. This paper comprehensively describes the geometric dimension of soil arching after the pile is qualitatively and quantitatively described, which is of certain reference value for further understanding the physical and mechanical properties of soil arching between piles. The article is divided into two parts. Firstly, the size of soil arching between piles is studied, and the existence form of soil arching between piles is analyzed preliminarily. Then, the factors that affect soil arching height are discussed in depth.
