抗滑桩截面形状优化选择

Selection Optimization of Section Shape of Anti-Slip Pile

利用FLAC3D软件,对矩形和圆形截面抗滑桩的支挡效果进行了定性分析,通过变量控制并结合土拱效应的相关理论,得出了在抗滑桩刚度相同或者横截面面积相等(经济成本和截面承载力相等)的前提下,在不同土质的砂土中,矩形截面抗滑桩较圆形截面抗滑桩所形成的桩后土拱更稳定,对滑体支挡效果更好,对抗滑桩截面形状的选择与设计有较大的参考价值。

This paper uses FLAC3D software,and it has rectangular and circular piles of section analysis and qualitative analysis respectively,and it has better effect on retaining wall through variable control and combining with the theory of soil arching effect,and it is concluded that for the same or equal cross section area in the pile stiffness（ economic costs and equal cross section bearing capacity） under the premise of sandy soil in different soil,there are rectangular section of anti-slide piles formed by a circular cross section pile been arch is more stable,and the better effect of the retaining wall of the sliding body,and the selection of the pile cross section shape and design have great guidance reference value.
