| 摘 要： | 在大型滑坡治理工程中常常采用双排抗滑桩,锚索双排桩和刚架双排桩是常见的两种型式。采用有限元程序ANSYS分别建立锚索双排桩和刚架双排桩的有限元分析模型,对比分析这两种型式双排桩的内力分布,找出能更好发挥抗滑效果的结构型式。通过对比分析可知,锚索双排桩的前后两排桩的内力分布差距十分明显,刚架双排桩的前后两排桩的内力分布差距较小,所以,刚架双排桩能够更好地发挥抗滑效果。选取锚索双排桩和刚架双排桩2个工程实例,监测分析发现锚索双排桩的前排桩侧向位移和弯矩均远小于后排桩,刚架双排桩前后两排桩的位移和弯矩比较接近,这与有限元分析结果相吻合,因此,双排抗滑桩的设计中建议采用刚架双排桩。 |

| Abstract: | Double-row piles are often used to the large-scale landslide.The anchor double-row piles and the frame double-row piles are the two common types.Based on the finite element program ANSYS,finite element models of the two types double-row piles are established separately.Compared the internal force distribution of anchor double-row piles with frame double-row piles,it is found that the frame double-row piles could be better able to play anti-slide effect.For the anchor double-row piles,the difference of inter... |
