摘要
采用ANSYS软件,对滑体的几何形态、滑带及滑体力学性质的差异对抗滑短桩的适用条件进行了研究。得出了如下结论:1)抗滑短桩更适用于滑体土强度明显高于滑带土强度的滑坡中。2)随着抗滑短桩的长度增加,滑坡设桩后的安全系数增大,但增大的幅度逐渐变小。3)在相同桩长的情况下,安全系数随着地形坡度的增大而变小。
Adopting ANSYS software, this paper analyzes the suitable conditions of short anti-sliding pile for different geometry shape of landslide body, landslide plane and different mechanic properties of landslide body. Some ideas are obtained ： 1 ） It is suitable to use short pile when strength of landslide body is obviously superior to strength of landslide plane. 2） The safety coefficient of landslide is increasing with increasing length of short pile, but the range of increasing is decreasing. 3 ） The safety coefficient of landslide is decreasing with increasing angle of slope at the same length of pile.
