摘要
基于桩后土拱效应理论,研究T形横截面抗滑桩(简称T形桩)对边坡加固效果的影响。通过ADINA有限元软件模拟,比较T形桩与其他形态横截面桩对滑坡土体位移的影响;分别探讨T形桩横截面后端宽度和前端宽度对桩土载荷比的影响及T形桩横截面高度对桩侧摩阻力分配比的影响。结果表明:T形桩对土体稳定效果最为显著。
The influence of T-shaped piles and other cross-section piles on the displacement of landslide was compared by finite element software ADINA ; The influence of the back-width and the front-width of the cross- section of the T-shaped pile on the load ratio of pile-soil is discussed respectively. The influence of the cross section height of the T-shaped pile on the distribution ratio of the pile side friction resistance was studied. The results show that the effect of T-shaped piles on soil stability is the most significant.
